Presbyopia Surgery Options

Presbyopia surgery is a presbyopia treatment option, if you are not satisfied with glasses or contacts. This type of presbyopia treatment includes several eye surgical procedures for improving presbyopia vision. Depending on your eye conditions, it can reduce or even eliminate your dependency on glasses or contact lenses.

Today there are many types of eye surgeries for presbyopia vision corrections: LASIK monovision, conductive keratotomy (CK), intraocular lens implants and Anterior Ciliary Sclerotomy (ACS). Below is a brief description on how non-laser and laser eye surgery works.

Laser Eye Surgery for Presbyopia

LASIK Monovision is one of the presbyopia surgery options that is approved by the FDA.

If you have normal vision, you look at an object with a binocular vision — when both your eyes work together. But you actually have one eye that delivers good distance vision and another one that provides better near vision.

In the mono vision arrangement, your “dominant eye” will work more for looking objects at the distance, and the other eye will work when looking near objects. In the same way, a LASIK surgeon will produce monovision in you. He or she will make your non-dominant eye slightly nearsighted to see up close.

As with contact lenses, many people with presbyopia experience discomfort with the absence of binocular vision. So, before going ahead with Monovision LASIK eye surgery, visit your doctor for a monovision contact lens fitting. Wearing monovision contact lenses are the best way to know whether or not you can adapt with mono vision arrangement.

Non-Laser Presbyopia Surgeries

Monovision with Conductive Keratoplasty (CK). Conductive Keratoplasty is approved by the FDA for the temporary improvement of near vision in people with presbyopia. CK uses radio waves in the circular pattern — made for surgery — to shrink some of the collagen in the cornea’s periphery. The circular treatment pattern acts like a belt that tightens around the cornea. It thus steepens the cornea for better near vision.

For monovision application, CK helps one of your eye see better near by and without touching another eye. If you were nearsighted, the other eye would wear a contact lens. As with the LASIK monovision you’d better wear monovision contact lenses before going ahead with CK.

Intraocular Lens Implants. The idea of lens implant is to replace the eye’s crystalline lens that has lost its focusing power. This is an easy presbyopia surgery decision for presbyopes who have cataract formation because there is no choice, the crystalline lens must be removed and replaced with multifocal intraocular lens. For younger presbyopia who have a clear crystalline lens the lens implant surgery requires a more careful decision.

The intraocular lens implants for presbyopia include the ReZoom multifocal lens and the ReSTOR lens. These two lenses provide far and near vision correction concurrently through the use of refractive and diffractive optics respectively. Another lens implant is the Crystalens. This accommodating lens implant achieves its focusing power by altering its position in the eye.

Anterior Ciliary Sclerotomy (ACS). ACS procedure is based on the theory that the cause of presbyopia is the lifetime continual growth of your eye lens. When you reach a certain age, the eye lens has grown to a size that it does not have room to change its shape — a change necessary in focusing on close objects.

To create more room for the lens to change shape, a surgeon makes radial pattern incisions on the sclera. The surgeon can perform ACS as an “off-label” procedure because it doesn’t use any unapproved devices or drugs.

Is Presbyopia Surgery Right for You?

Presbyopia gets worse as you get older. Thus, having monovision LASIK procedure before your presbyopia reaches its peak is not a good idea. So, postpone your eye surgery until it’s level out at the age range of 50 and 65.

Being minimally invasive is the main benefit of CK surgery. Although some patients report to have vision fluctuation, normally it’s only temporary. Because there is a probability for an enhancement procedure later, with CK you may change prescription and with ACS there is enough room for the lens to change shape as the presbyopia progresses.

Many eye surgeons are reluctant to perform intraocular lens implant in people without cataracts because of the risks involved in any eye operation. These risks include a very small chance of infection that may lead to blindness. What’s more, this surgical procedure will not produce clear 20/20 vision.

So, which procedure will suit your needs? Consult your local eye surgeon for the best presbyopia surgery option.
