Learn how Cohen Eye Associates, Limited, in St. Louis, MO, can enhance your quality of life with IOL refractive surgery. 

How Intraocular Lenses Work

              Artificial Lenses


Intraocular lenses are artificial lens implants that are made of a safe and comfortable clear plastic. These lenses are custom designed to enhance your eyesight and are often placed as part of cataract surgery.

Supplements the Natural Lens


These artificial lenses have different uses. While some IOLs fit atop the natural lens of the eye, other IOLs completely replace the lens. In either case, patients can experience improved vision thanks to these implants.

Good Candidates for IOL Refractive Surgery

During your visit to one of our St. Louis offices, we will determine if intraocular lenses are right for you or whether another refractive surgery, like LASIK or PRK, is a better choice. We often use these implants to help the following types of patients:

People with Cataracts

A cataract occurs when the lens contains a buildup of protein. Cataract surgery removes the clouded lens. An IOL can be placed during the procedure to restore clear vision.

People with Myopia (Nearsightedness)

Nearsightedness refers to difficulty seeing objects that are up close. IOLs can treat myopia without the need for glasses or contacts. In some cases, it is an advisable alternative to LASIK surgery.

People with Astigmatism

Often accompanying myopia, astigmatism is an imperfection in the curvature of the cornea that affects focus. IOLs can be used to treat astigmatism.

People with Presbyopia

Presbyopia is an age-related form of hyperopia (farsightedness). Rather than getting bifocals or monovision LASIK, some patients with hyperopia opt for intraocular lenses. If you have had a refractive surgery like LASIK in the past, you should still be eligible.

Types of Intraocular Lenses

Cohen Eye Associates is proud to offer standard and premium lens implants based on the needs of the patient. Broadly categorized, our practice has lenses that are monofocal, multifocal, and toric.

Monofocal IOLs

Monofocal IOLs are lenses that correct vision for only one distance: near, intermediate, or far-off distances. If you do get monofocal IOLs, you will still need prescription glasses to be able to see clearly at other distances. These lenses are typically covered by insurance.


Multifocal IOLs

Multifocal IOLs allow you to see at multiple distances. Some multifocal IOLs have visual zones and function similar to bifocals. Other IOLs are accommodating and mimic the movements of the natural lens of the eye.


Toric IOLs

Toric IOLs are designed for people who suffer from astigmatism. Toric lenses are not flexible yet still help refract light at different distances. The unique design of the toric lens implant helps address irregular corneal shape.

I have really enjoyed my experiences at Cohen Eye Associates. Dr. Buchner is a spectacular physician with a great touch. I couldn’t even see out of my right eye and now I have 20/20 vision. Tomorrow I will have my left eye done and I expert to be without glasses for the first time in 50 years.

IOL Refractive Surgery  Treatment Timeline

Thanks to state-of-the-art IOLs, you could live free of glasses and contacts.

Assessing Your Candidacy

During your initial visit, we perform a full eye exam, discuss your vision goals, and answer questions. We can also compare intraocular lens results with LASIK, and discuss cataract surgery in detail.

Numbing the Eye

Once you are approved, we can schedule your surgery. To begin, numbing eye drops are placed to reduce any pain. Patients can also be given a local anesthetic to help minimize discomfort around the eyes. General anesthesia can be used in some circumstances.

Removing the Lens

If you are undergoing cataract surgery, the natural lens must be broken up and extracted through a small incision. This is done using a safe laser or ultrasound probe. Whenever possible, the clouded lens is removed while leaving the capsule intact.

Placing the IOL

Many lens implants can be folded and inserted through the small incision for proper positioning. Larger incisions are needed for lens implants that cannot be folded. The entire procedure takes approximately 15 minutes.

The Cost of IOLs Insurance, Payment, and Financing Options

Insurance Coverage

At Cohen Eye Associates, Limited, we accept a variety of HMO and PPO insurance plans. We can help you check coverage eligibility and will file insurance forms on your behalf. Monofocal lenses are generally covered while premium lenses are not.

Payment Methods

Paying for eye procedures should be simple. That's why we accept checks and major credit cards. We can also discuss ways to break up the cost of your care. We believe everyone deserves access to crystal clear sight.

Financing Options

Financing options can make multifocal and other premium lenses more affordable. Thanks to CareCredit® financing, the total cost of treatment can be split into monthly installments with a reasonable interest rate applied.

I have been going to Cohen Eye Associates for some years for regular exams. The last time, I was told I needed cataract surgery. I had the same trepidation that many people have when they hear that they need surgery on their eyes, but it was easy and painless. I am delighted to be able to drive again without glasses. Cannot speak too highly about my experience.
