Clinical Trial Summary

Aim of the study is to evaluate outcome of cataract surgery in different types of uveitis as regarding best corrected visual acuity (BCVA) and rate of post operative complications.


Description:

Cataract is the main cause of reversible blindness in patients with uveitis. Cataract occurs in up to 50% to 70% of patients with uveitis.

Preoperative complications, including anterior synechiae, posterior synechiae, and pupillary membrane formation, may increase surgical challenges. In addition, recurrent inflammation increases the incidence of postoperative complications and often affects the visual prognosis. In recent years, phacoemulsification with intra ocular lens (IOL)implantation has become the main surgical method for treating uveitis (complicated cataract), and the visual prognosis of patients who undergo this procedure is usually favorable.

Surgical treatment may be effective but is associated with higher rates of complication than in non uveitic eyes. Cystoid macular edema (CME) is the most common complication cataract surgery in the general population. Although, in most cases, the macular edema is self-limited, in rare cases it can lead to long-term visual deterioration that is difficult to treat.

Another common complication after cataract surgery is posterior capsule opacification (PCO) , leading to symptoms of glare or blurred vision, reduced visual acuity, or impaired posterior segment exam. Factors that are critical in the development of PCO include surgical technique, type of implanted intra ocular lens (IOL) either foldable hydrophilic acrylic, hydrophobic acrylic or silicone and postoperative control of uveitis
