Other Eye Conditions That May Impact Cataract Surgery

A cataract occurs when the human lens, made primarily of protein and water, becomes clouded. This clouding prevents some light and images from reaching your retina, thereby impacting your ability to see clearly. Injury to your eye, certain diseases, and even certain medications can cause the clouding. However, in more than 90 percent of cases, cataracts are caused by aging. If you have a cataract, it can be safely and successfully removed through cataract surgery.

Eyes.com is dedicated to providing a wide range of information about eye conditions and refractive surgery options, and can help you find an eye doctor who can meet your vision needs.

There are several eye conditions that may impact the results of your cataract removal surgery. Be sure to discuss any eye conditions with your ophthalmologist and know the risks involved before undergoing this procedure.

Vitrectomy

Your vitreous humor is the clear gel-like substance that comprises most of your eye. A vitrectomy is a procedure that removes your vitreous humor to relieve pressure on your retina, if you have a retinal detachment or any type of injury, or to heal infections that do not respond to other therapy.

If you have a vitrectomy, you are at risk for developing a cataract after surgery, especially in the first several years following the procedure. Cataracts can safely be removed after you have undergone vitrectomy, but you should be aware of this potential.

High Myopia

If you have high myopia (nearsightedness), the placement of an intraocular lens (IOL) during cataract surgery will actually help correct your vision. However, patients with high myopia who have a cataract removed are at an increased risk of developing:

Macular degeneration
Retinal detachment
Flashes and floaters
Veils and curtains

If you develop one of these conditions post-operatively, you may need to undergo another procedure to correct your vision. Also keep in mind that it is virtually impossible for myopic patients to obtain 20/20 vision following successful cataract surgery, because of myopic macular degeneration.

Pterygium

A pterygium is a raised growth in the surface of the eye (the conjunctiva), comprised of collagen and tiny red capillaries. It is usually caused by extended exposure to sunlight and may grow, become inflamed and impact your vision. Many ophthalmologists recommend having a substantially-sized pterygium removed before cataract surgery. However, the decision will vary by patient, based on the severity of your growth, and how bad your cataract is.
