Vision-Correction Surgery

Man Smiling

When people think of surgery to correct vision, they usually think “LASIK.” LASIK is truly remarkable technology. It can have a profound impact on the quality of life of patients. But some people may not be LASIK candidates. Excessively high degrees of nearsightedness, farsightedness or astigmatism may simply be beyond what LASIK can effectively treat. Other issues such as a thin cornea, early cataract development, or corneal disease or advanced dry may be reasons a person cannot have LASIK. Fortunately there are other solutions that can be just as effective.

What is Vision-Correction Surgery?

Vision correction surgeries provide an alternative to LASIK for people who are not LASIK candidates and who want to gain greater visual freedom from glasses and contacts. Vision correction surgery is a variety of procedures including ICL, Kamra inlay, and refractive lens exchange. Each of these procedures addresses different issues that may make a patient a non-LASIK candidate.

What Are the Different Types of Vision-Correction Surgery?


A remarkable technology that is established but continues to evolve for patients who are not good candidates for LASIK is the Visian ICL. ICL, which stands for implantable collamer lens, is a corrective lens which is placed inside the eye behind the iris. It is transparent and not visible to anyone looking at your eyes. The Visian ICL is manufactured by Staar surgical.

The ICL is made from a collagen and synthetic polymer. It is very gentle and well-tolerated by the eye. It first gained FDA approval in about 2005 and is currently on its third-generation and most recently has been FDA approved for correction of astigmatism as well as nearsightedness. It has also been adopted by the US military as an alternative to LASIK.

The ICL can treat moderate to severe degrees of myopia well beyond the upper limits of what LASIK is capable of treating. It is also ideal for patients who have moderate to severe dry eye problems as it usually has a very mild impact on dry eye. Vision recovery is usually very rapid after ICL placement – usually within 24 to 48 hours after surgery. Vision outcomes are comparable to LASIK. ICL also has the advantage that it can be removed if new technology develops in the future.

As with any medical procedure there are also risks inherent to ICL placement. ICL surgery is more invasive than LASIK. A small subset of patients (<3%) can develop cataract, acute glaucoma and corneal clouding after surgery. Because it is a medical device patients also need annual follow-up to ensure that they have continued good eye health after surgery.

Refractive Lens Exchange

For patients with very high degrees of nearsightedness or farsightedness or for patients with some early cataract development and who are age 50 and above, refractive lens exchange is a surgical option that can improve distance vision without glasses and can even help restore near vision.  Using new technology lens implants, distance, intermediate and near vision can be simultaneously in focus.

Refractive lens exchange is performed much like cataract surgery by removing the natural lens of the eye and replacing it with a new lens implant which has the correct strength to properly focus your vision.  Using multifocal designs, your near and intermediate vision as well as astigmatism can also be treated at the same time. 

We are using the latest in lens implant technology including the Panoptix trifocal IOL, Vivity progressive IOL and Eyehance multifocal IOL from Alcon Labs and Johnson & Johnson Vision.  Patient satisfaction rates while not perfect with these lenses are very high with most patients satisfied or very satisfied with their vision after surgery. 

For patients over 50 with mild cataracts (to the degree they are not impairing vision with glasses), refractive lens exchange is often the better alternative to LASIK because it has the all of the visual benefits of LASIK and more but eliminates the need for cataract surgery later in life.  In this way refractive lens exchange lowers cost and reduces overall surgical risk.

Kamra® Inlays

Kamra inlays were developed to correct poor reading vision in people over age 45. The micro-thin Kamra inlay is placed underneath a LASIK flap or in a pocket within the cornea. It functions in the same way that cameras on a cell phone do. Kamra inlays create a small aperture in the cornea, blocking out unfocused light and only allowing focused light to enter the eye.

The optical technique used by Kamra inlay increases what is known as depth of focus. This restorative procedure improves near vision and can reduce or eliminate the need for reading glasses.

To find out if you are candidate for Kamra inlay surgery call to schedule your free screening at Sun Laser Vision Center.
