Visian ICL, or “implantable Collamer lens” is an alternative procedure for patients who may not be ideal candidates for Lasik or other alternative corrective eye surgery. Visian ICL is typically used for patients who do not want to remove portions of their cornea, have thin corneas, or that have excessively high levels of nearsightedness (myopia).

This procedure makes a small incision and then implants a personalized prescription lens over the cornea to allow for corrected vision. If your vision then changes due to aging or other natural processes, the lens can be replaced by another lens with an updated prescription.
 

Who is a Good Candidate for ICL?

Typically, patients that would benefit from ICL are between the ages of 21-45. This age represents a slight increase from the base age of 18 for Lasik. This procedure is also not well suited for geriatric or elderly individuals. Patients may also have mild or severe myopia, and they have a prescription that has been relatively unchanged. While the age requirements are more stringent for ICL than Lasik, there are other less stringent qualifications. This means that even if you aren’t an ideal candidate for Lasik, ICL could be a good option for you.
 

Performing the Operation

ICL is considered an outpatient operation and only takes about 30 minutes to complete. This means that you will be in and out of your chosen facility on the same day. Patients are given some numbing drops for their eyes and individuals that are more hesitant or uncomfortable may also be given a sedative. 

The surgeon will make several micro-incisions in the eye to insert and place the lens. When the lens has been inserted, it will be unfolded, and the edges of the lens will be placed behind the iris. After this is completed, the operation is considered complete. Your physician may give you some eye drops for postoperative care and then send you home. There may be a follow-up appointment scheduled 24 hours later.
 

Post-Operation

After your operation, you will be required to have somebody else drive you home. Anytime that you have an operation that may impair your vision or ability to operate a vehicle, you should plan to have somebody else drive you home. Surgery results are typically noticeable 24 hours after the operation.

Recovery time is minimal, and some patients experience mild discomfort or a gritty feeling in their eyes. Your doctor may require you to stay out of the swimming pool and avoid activities that make you heavily perspire because when sweat gets into your eyes, it may aggravate the micro incisions and cause additional discomfort.

While there are some potential complications both during and after the operation, they are typically minimal. The chances of impairing your vision or causing long-term damage are very low with this operation, however, you should make sure to talk about potential side effects with your physician. If you experience any abnormality, you should seek medical attention immediately.
 

LASIK (laser-assisted in situ keratomileusis), is the most popular refractive surgical procedure. In this procedure, a laser is used to permanently change the shape of the cornea (the clear covering on the front of the eye) to correct common vision problems such as nearsightedness, farsightedness, astigmatism, and presbyopia. This improves vision and reduces a person's need for glasses or contact lenses.

LASIK uses an excimer laser (an ultraviolet laser) to remove a thin layer of corneal tissue, giving the cornea a new shape, so that light rays are focused clearly on the retina. In the case of a nearsighted person, the goal of LASIK is to flatten the too-steep cornea; with farsighted people, a steeper cornea is desired. LASIK can also correct astigmatism by smoothing an irregular cornea into a more normal shape.

LASIK is an outpatient surgical procedure with no need to stay at the surgery center overnight as it will take 10 to 15 minutes to perform for each eye. The procedure is done while the patient is awake, but the patient may request mild sedation. The only anesthetic used is eye drops that numb the surface of the eye. LASIK can be done on one or both eyes during the same session.

How to Prepare for LASIK Eye Surgery?

Before LASIK eye surgery, the eye surgeon will evaluate the patient’s medical history and perform a full eye examination, including measuring corneal thickness, refraction, corneal mapping, eye pressure, and pupil dilation. Afterward, the surgeon will discuss what to expect during and after the procedure.

On the day of the surgery, eat a light meal before going to the doctor and take all prescribed medications, if any. Do not wear eye makeup, creams, perfumes or lotions on the day before and the day of surgery, or have any bulky hair accessories that will interfere with positioning head under the laser.

Contact lenses shouldn't be worn for at least three days prior to the evaluation. In the case of, rigid gas permeable contact lenses, they should not be worn for at least three weeks before. Patients should arrange for a ride home from the place of surgery, as their vision might be blurry.
 

Millions of patients are diagnosed with diseases and conditions of the eye every year. Some of which may not display symptoms until there is irreversible damage to the patient’s vision. The outcome of eye disease can range from temporary discomfort to total loss of vision, which is why all eye problems and diseases should be taken seriously and regular eye check-ups are absolutely essential.
 

What Are The Causes of Eye Disease?

The main causes of eye problems can be divided into five groups:

• Inflammation of the eye and surrounding structures caused by a bacterial, viral, parasitic or fungal infection.

• Injuries to the eye and surrounding structures, either as a result of trauma or an object in the eye.

• Genetically inherited eye diseases, many of which may only manifest later in life and affect the structures and the functioning of the eye which therefore can impair visual abilities. In some cases, however, children are born with these conditions.

• Diseases or conditions, such as migraine or diabetes, which can affect other organs of the body, such as the eyes.

• External causes, such as allergies or eye strain due to over-use, or as a side effect of medication.
   

What Are The Symptoms of Eye Disease?

The three symptoms indicative of eye disease are changes in vision, changes in the appearance of the eye, or an abnormal sensation or pain in the eye.

Changes in vision can include the following symptoms:

• Nearsightedness is caused by an elongation of the eyeball over time, making it difficult to clearly see objects far away.

• Farsightedness is caused by the shortening of the eyeball, making it difficult to see objects that are close-by clearly.

• Blurry or hazy vision, or loss of specific areas of vision, which can affect one or both eyes and is the most common vision symptom. Any sudden changes in vision should be a cause of concern.

• Double vision means a single clear image appears to repeat itself. This could be accompanied by other symptoms like headaches, nausea, a droopy eyelid, and misalignment of the eyes.

• Floaters are specks or strands that seem to float across the field of vision. These are shadows cast by cells inside the clear fluid that fills the eye. These are usually harmless, but should be checked out as they could point to something serious such as retinal detachment.

Eye disease that is caused by diabetes is currently the number one cause of blindness and vision loss. Due to the increased risk in diabetic patients, doctors recommend that people over 30 with diabetes get an annual dilated eye exam. Diabetic patients under 30 should get this exam five years after they have been diagnosed.

Diabetic retinopathy is a condition that is caused by damage to the retina. Patients that have diabetes may also have experienced extended periods of time where their blood sugar was elevated. The high levels of blood sugar damage the retina’s walls which leave them susceptible to leaking. When fluid accumulates in the retina or macula, it causes vision loss.

To make these matters worse, if prolonged high blood sugar levels are seen again, the retina will be oxygen-depleted. This causes the abnormal growth of new blood vessels. This condition is called neovascularization. This blood vessel type is weak and prone to leaking. As these blood vessels leak, they introduce blood into the eye. Excessive bleeding into the eye can cause blindness.
 

Treatment

While a healthy diet and exercise can be beneficial to your optical health, diabetic retinopathy is a condition that is caused by damage to the retinal wall. While this damage can sometimes be corrected, simple diet changes won’t reverse the effects.

It is essential to catch the condition in the earlier stages to reduce the effects. This can also help patients understand the importance of monitoring their blood sugar so that repeat events can be limited. Treatment options are even more successful when diabetic retinopathy is caught early. These options include vitrectomy, scatter photocoagulation and focal photocoagulation.

During both scatter, and focal photocoagulation the doctor will use lasers to help alleviate the condition. The lasers make small burns on the retina aimed at the blood vessels. These burns will help to seal the blood vessels to prevent more leakage and stop them from growing larger.

When using scatter photocoagulation, hundreds of small burns are made in a specific pattern during two additional appointments. Scatter coagulation should be used on patients who do not have advanced diabetic retinopathy.

Focal photocoagulation specifically targets the leaking blood vessels that are in the macula. Unfortunately, this procedure is not aimed to correct the blurry vision associated with diabetic retinopathy, but it does stop it from progressing further. Once the retina has detached, neither form of photocoagulation can be used.

Vitrectomy is a surgery that helps to remove scar tissue and/or the fluid that is clouded with blood that has been leaked into the eye. This operation is the most successful when performed before the disease has progressed too far. When the operation only targets removing the fluid, success rates are very high for the procedure. When the procedure also aims to reattach the retina, the failure rate is around 50%.
 

Premium IOLs or intraocular lenses are lenses that are placed in the eye during cataract surgery. The lens placement is designed to restore the natural lens shape. These lenses can also be placed as a vision correction device called refractive lens exchange. Premium IOLs offer advanced features beyond the single vision IOL’s that are also offered. These features include aspheric, toric, accommodating, and multifocal IOL’s.
 

Understanding Premium IOL Types

Aspheric Lenses

These lenses closely match the natural curve of the eye. Typical lenses were uniformly curved making it easier to manufacture, but at the same time increasing the chance of causing imperfections in vision. Aspheric lenses help to reduce imperfections and improve clarity, especially at nighttime.
 

Toric IOLs

These lenses are specifically designed to help correct nearsightedness, farsightedness, and astigmatism.
 

Accommodating IOLs

Accommodating IOL’s can tilt slightly forward when you look at objects that are close to the eye. This helps to improve visibility when you are performing actions like reading a book. While they are not necessarily as sharp as bifocals, patients have a reduced need to use reading glasses while still maintaining excellent distance vision.
 

Multifocal IOLs

If you require a bifocal or trifocal lens in your glasses, this may be a likely choice for you. Different portions of the lens allow for better vision at different ranges. However, there are some overall sacrifices with vision clarity at a distance.
 

History of Premium IOLs

Premium IOLs have been approved by the Food and Drug Administration (FDA) since the 1980s. Prior to FDA approval, when patients had cataract surgery, they were required to wear very thick eyeglasses or specialized contact lenses to correct their vision. New technologies in the optical world have allowed for a wide variety of available premium IOLs and figuring out which specific type that suits you best will depend on some different factors.
 

Patient Factors

Physicians are careful to discuss the realities of this procedure with their patients. After recovering from cataract surgery, many patients expect that their vision will be completely restored to their peak performance. However, doctors are careful to warn against this and explain the realities of the surgery and as well as likely expectations of what will result from the surgery. For this reason, surgeons are likely to have some initial concern about the desired outcome for the patient to make sure that their hopes are grounded.

Surgeons will also have an eye toward the patient's desire to not wear eyeglasses. If the patient does not mind wearing corrective lenses without the need for surgery, this may be the best option. These lenses may also not be an ideal fit for the elderly population. Eyes in the geriatric population are often rapidly deteriorating requiring a lens replacement more quickly than would be recommended.

Patients with certain medical histories may also be poor candidates for premium IOL surgery. Some of these conditions include:

• Advanced macular degeneration

• Anterior basement membrane dystrophy

• Fuch’s dystrophy

• Weak zonules

• Glaucoma

• Post-refractive surgery patients
   

This list is not comprehensive, so it’s important to consult with your physician and bring a detailed medical history for their review.

Finally, patients may also want to consider their careers when weighing the value of this surgery. Patients who are required to read on computer screens for extended periods of time (i.e., print editors, office jobs) may be ideal candidates.

In contrast, individuals that require long-distance acuity like truck drivers, pilots, or even photographers may find that some of the issues with these lenses are not suited to their needs. Individuals often complain of “halos” during the night when looking toward a light, glare, or general acuity issues at longer distances.
 

Further Consideration

While premium IOLs do have some limitations, they offer an excellent choice for many individuals. However, it is important to meet with your eye care professional to fully discuss all of the available options to find your best fit as well as to make sure that you understand all of the potential risks and restrictions that this operation poses.

PRK or photoreactive kerectomy is a surgical procedure that was the precursor for the surgery known as Lasik. The biggest difference between the two procedures is how the first portion of the operation is conducted. Additional variability between the two procedures includes recovery, risk factors, and the patient’s overall needs. Understanding these differences can help you decide if PRK is an appropriate solution for your vision issues.
 

How it Works

PRK utilizes a laser to correct farsightedness (hyperopia), nearsightedness (myopia), and astigmatism. During a PRK operation, a laser is used to remove the exterior epithelial cells from the cornea. This procedure uses an excimer laser to remove the cells which are then discarded. A contact “bandage” is placed over the eye, and the cells can heal over the course of a few days. Your doctor will then remove the contact lens when the eye has healed enough to be exposed.

While the results are like that of Lasik, PRK does take some additional healing time. This is due to the time that must be allowed for the epithelial cells to heal and regrow on the eye. Additionally, Lasik patients generally experience less discomfort and faster results. PRK results can take a few weeks to fully materialize.

This isn’t to say that PRK doesn’t have its own benefits too. This procedure is well-suited for patients that have had previous eye surgeries and may have thin corneas. Because PRK does not make an incision into the cornea and only removes the epithelial cells, it leaves more of the stromal tissues which underly the epithelial tissue. PRK does not run the risk of “flap” issues that can arise from Lasik, and the risk of removing too much of the cornea is reduced. However, if you are considering PRK, you should consult with your medical professional to identify the right procedure for your specific case.
 

Before the Surgery

When you meet with your eye specialist to discuss your options, there are several factors that they will consider. Your potential surgeon should conduct a thorough eye exam during which they will measure your eye moistness, pupil size, corneal thickness, and corneal curvature. Your doctor should also review your medical and family history to identify any possible concerns about your suitability. Make sure that you bring a list of your medications and previous operations. Finally, you may be required to stop wearing contact lenses for a period before the operation. This can allow your cornea to return to its natural shape before the operation.
 

The Surgery

The actual PRK surgery is a short procedure that will only take about 15 minutes. The patient will not be sedated during the operation but may be given an oral sedative that helps to relax the eye. Numbing drops are applied to your eyes and a small speculum is also used to hold the eyelids open for the procedure. The excimer laser is programmed for your exact eye prescription. Patients are instructed to look at a certain object or target while the laser is operating. The surgeon will watch the procedure through a microscope and can stop the procedure at any time. Most patients do not report discomfort, although there may be some pressure.
 

Recovery

You will be observed for a short time after your operation to make sure that you don’t have any severe immediate reactions. After this observation, you will be sent home. It is important to have someone else drive you after any procedure that may impact your vision or ability to drive safely. You should make sure to follow all of the doctor’s recommendations to facilitate a speedy recovery. You should also expect several follow up appointments to make sure that the operation was successful and that there are no additional concerns.

Your full results may take several weeks, but almost all patients have vision that is 20/40 or better. Over time, as the eye ages, vision may naturally degrade. At this time, you should consult with your medical professional to see if an additional operation is a good option for you.

If you’ve been diagnosed with glaucoma, you’re probably already familiar with the typical options in glaucoma treatment – eye drops, laser treatment or traditional surgery. While these are certainly effective, especially when glaucoma is diagnosed early, researchers have been working hard to offer new glaucoma treatments. Their goal is not only to improve outcomes but also reduce the treatment’s side effects and frequency of use.
 

What is the Goal of Glaucoma Treatment?

Before we dive into the new options, it’s important to understand the goal of any glaucoma treatment. At present, glaucoma is not curable. However, treatment can significantly slow the progression of the disease. Glaucoma damages your eye's optic nerve. Extra fluid builds up in the front part of your eye (cornea), which increases the pressure in your eye. Reducing this pressure is the primary objective of any glaucoma treatment. This is often referred to as intraocular pressure or IOP.
 

What are the Limitations of Standard Glaucoma Treatments?

Eye drops for glaucoma treatment seem like an easy option but there are several challenges that can reduce its effectiveness. It can be difficult to get all the medicine in the eye, especially for older adults with less of a steady hand. In addition, since it must be applied daily, individuals may forget. Since the drops have no perceivable benefit because early stages of glaucoma have no symptoms, patients might make it a lower priority which is understandable since it may also have unpleasant side effects like burning, red eyes.

Beyond eye drops, laser surgery is a less invasive option. The laser opens clogged tubes and drains fluid. It can take a few weeks to see the full results. If laser surgery or drugs don’t relieve your eye pressure, you may need a more traditional operation. You would have to go into the hospital and will need a few weeks to heal and recover. Although usually effective, glaucoma surgery can make you more likely to get cataracts later on. It can also cause eye pain or redness, infection, inflammation, or bleeding in your eye.

What are Recent Advances in Glaucoma Treatment?

Alternatives or Improvements to Eye Drops
The Glaucoma Research Foundation reported several new developments on the horizon. These technologies focus on reducing patient error in applying eye drops which would make the medication more effective and improve the quality of life for the patient. Here are some of the products underway:

• A polymer, like a contact lens, would contain the drug; it would sit under the eyelid and release the medication over several months

• Microneedles would inject medication into a specific spot to be most effective

• Implantable extended-release devices using engineered highly precise microparticles and nanoparticles

• Polymer-based intraocular delivery technologies that would allow customizable sustained release

• Drops that allow the medication to get into the eye more easily

• Tear duct plugs that release medication

In addition, people with glaucoma who take more than one eye drop per day are beginning to see those medications available as a single, combined eye drop. New products include Cosopt (timolol and dorzolamide), Combigan (timolol and brimonidine) and Simbrinza (brinzolamide and brimonidine).
 

Senior eye care is crucial for maintaining optimal vision and overall eye health as we age. As individuals grow older, they become more susceptible to age-related eye conditions. Regular comprehensive eye exams play a key role in early detection and management of these conditions, helping to preserve vision and prevent potential vision loss. By staying proactive with eye care and seeking timely professional assistance, seniors can enjoy clear, comfortable vision and ongoing eye health for years to come.
 

Common Eye Conditions in Seniors

As we reach our golden years, there are several eye conditions that become more prevalent. These conditions can have a significant impact on our vision and overall quality of life.
 

• Presbyopia: This condition affects near vision, making it difficult to focus on close objects. It is a normal part of aging and is typically addressed with reading glasses or multifocal lenses.

• Floaters and Flashes: As the vitreous inside the eye changes with age, it can lead to the perception of floaters (small dark spots or lines) and flashes of light. While often harmless, sudden onset of floaters and flashes may indicate a retinal tear or detachment and should be promptly evaluated.

• Age-Related Macular Degeneration (AMD): AMD is a leading cause of vision loss in older adults. It affects the macula, the central part of the retina, leading to blurred or distorted central vision. There are two forms of AMD, dry AMD, and wet AMD, with the latter being more severe.

• Cataracts: Cataracts are a common age-related condition characterized by the clouding of the eye's natural lens. This can lead to blurry vision, glare, and difficulty seeing in low-light conditions.

• Glaucoma: Glaucoma is a group of eye conditions that damage the optic nerve, often due to elevated intraocular pressure. It can result in peripheral vision loss and, if left untreated, may lead to total blindness.

• Diabetic Retinopathy: For seniors with diabetes, diabetic retinopathy is a concern. It occurs when high blood sugar levels damage the blood vessels in the retina, leading to vision problems and potential blindness if not managed.

• Dry Eye Syndrome: Seniors may experience dry eye syndrome, characterized by insufficient lubrication and moisture on the surface of the eye. It can cause discomfort, redness, and fluctuating vision.
  
   

Clear Lens Extraction (CLE) is a surgical procedure that involves the removal of the natural lens of the eye and replacing it with an artificial lens implant, also known as an intraocular lens (IOL). CLE is primarily performed to correct refractive errors, such as nearsightedness, farsightedness, and astigmatism.
 

Understanding CLE and How It Works

Clear Lens Extraction is similar to cataract surgery, where the natural lens is removed and replaced with an IOL. However, in CLE, the lens is clear and not clouded as in the case of cataracts. The procedure begins with the administration of local anesthesia to numb the eye and ensure a painless experience for the patient.
 

Once the eye is numb, a small incision is made on the cornea, which is the clear front surface of the eye. Through this incision, your eye surgeon accesses the lens and carefully removes it. The artificial IOL is then inserted into the empty lens capsule. The IOL is specifically chosen to correct the patient's refractive error, providing them with improved vision.
 

After the IOL is implanted, the incision is closed with tiny sutures or self-sealing techniques. Following the surgery, patients are usually prescribed antibiotic and anti-inflammatory eye drops to prevent infection and reduce inflammation.
 

Factors to Consider Before Undergoing Clear Lens Extraction

Before deciding to undergo Clear Lens Extraction, there are several factors that need to be considered. Firstly, it is crucial to have a thorough eye examination to determine if you are a suitable candidate for the procedure. Your optometrist will evaluate your overall eye health and discuss your expectations and goals for vision correction.
 

Age is another important factor to consider. CLE is typically recommended for individuals over the age of 40 who have developed presbyopia, a condition that affects near vision. It is also important to have stable vision, as any changes in prescription can affect the accuracy of the IOL power calculation.
 

Additionally, it is essential to understand the potential risks and complications associated with the procedure. While CLE is generally safe, there is a small risk of infection, bleeding, and retinal detachment. Your optometrist will discuss these risks with you and address any concerns you may have.

Urgent eye care encompasses prompt evaluation and treatment of sudden or severe eye-related issues, including foreign object removal, chemical exposure, corneal abrasions, sudden vision loss, eye trauma, acute glaucoma, chemical burns, and eye infections. Seeking immediate professional attention from an optometrist is vital to prevent further damage and preserve vision.
 

Common Eye Emergencies or Urgent Eye Care Appointments

Eye emergencies can manifest in various forms, and it is essential to be able to identify them quickly. Some common eye emergencies include:
 

• Foreign Object in the Eye: Particles, debris, or small objects can become lodged in the eye, causing pain, redness, tearing, and potential damage to the eye's surface.

• Corneal Abrasions or Scratches: Injuries to the cornea, such as abrasions or scratches, can cause severe eye pain, light sensitivity, and a feeling of something in the eye.

• Sudden Loss of Vision: Any sudden and unexplained loss of vision requires immediate attention to determine the underlying cause and initiate appropriate treatment.

• Eye Trauma or Blunt Force Injury: Injuries to the eye from impact, trauma, or accidents can lead to serious complications, including retinal detachment, hemorrhage, or intraocular foreign bodies.

• Chemical Burns: Exposure to caustic substances or chemicals can cause serious damage to the eyes, resulting in pain, redness, and potential vision loss.

• Eye Infections: Infections such as conjunctivitis (pink eye) can cause redness, discharge, and discomfort in the eyes.
   

Recognizing these symptoms and seeking urgent care can prevent further complications.
 

The Importance of Basic Red Eye Exams in Urgent Care

Red eye exams are a fundamental part of urgent eye care. They help identify the cause of redness and determine the appropriate treatment. Basic red eye exams involve a comprehensive evaluation of the eye, including examining the eyelids, conjunctiva, cornea, and iris. These exams aid in the diagnosis and treatment of various conditions, such as conjunctivitis, uveitis, dry eyes, and corneal abrasions.
