Vitrectomy Cataract Removal

The human eye is made up of a number of parts. The substance that separates the lens, which focuses the eye, from the retina is known as the vitreous humor, a clear gel-like matter that fills most of the eye. A vitrectomy may be performed in individuals who suffer from a lack of clarity in the vitreous, to fix scars, or to relieve pressure on the retina. Doing so, unfortunately, may cause cataracts that further impair the function of an individual's eye.

Why Have a Vitrectomy

• Any number of conditions may necessitate a vitrectomy, the removal of the vitreous gel from the rest of the eye. Retinal detachment or fibrosis are common causes, while others require such surgery to repair bleeding, injuries to the eye, or persistent infections that do not respond to other forms of therapy. The eye is then sealed with a replacement for the vitreous, usually a gas bubble or silicone oil. While this often causes discomfort, further complications must be reviewed by a doctor in case additional surgery is necessary.

Complications

• Complications may require further surgery in order to fully repair an eye. Vitrectomy may necessitate cataract removal due to a nuclear sclerotic cataract, a complication due to the lens of the eye hardening following surgery. Vitrectomy often leads to cataract formation, or the acceleration of cataracts already present in the eyes of certain individuals. This problem makes it difficult for patients after a vitrectomy to see clearly. Because such surgery may not result in the full restoration of perfect sight, some doctors recommend the use of bifocal contacts following vitrectomy cataract removals.

IOL Procedure

• Following vitrectomy cataract removal, many patients continue to need corrective lenses or glasses. In order to alleviate the problems of cataract surgery following a vitrectomy, many doctors recommend the use of an IOL--an intraocular lens--which is placed into the eye permanently and used to improve vision if a lens is damaged. The procedure is normally done after the initial surgery to remove a cataract results in imperfect vision, and can decrease the dependency of the individual suffering from sight issues after vitreous removal. Bifocal lenses can also help a person to see more clearly following vitrectomy cataract removal, although many patients may opt for a surgical implantation that will improve eyesight from all distances and under any condition.
