Abstract

Cataract is a commonly encountered complication of uveitis. Its development may be correlated with duration, chronicity and location of the inflammation as well as the use of corticosteroids. The incidence of cataract in uveitis varies from 57% in pars planitis to 78% in Fuchs’ heterochromic iridocyclitis (FHI). Cataract surgery in these patients is usually quite complex. The type of uveitis determines the final outcome. Certain uveitic diseases have a good to excellent visual prognosis. A proper preoperative assessment includes comprehensive ocular and systemic history, complete ocular examination and relevant systemic examination. Optical Coherence Tomography can additionally help in quantification of macular oedema or atrophy, detection of epiretinal membranes and vitreofoveal traction. B-scan ultrasonography is an invaluable tool in assessment of the posterior segment. The primary goal of surgery is of course to improve vision. However, successful visual outcome depends not only on successful surgery but also on pre-existing irreversible structural damage. Factors which would adversely affect the visual outcome include presence of concurrent glaucoma or hypotony, band shaped keratopathy, extensive posterior synechiae, retinal detachment, optic atrophy, cystoid macular oedema, macular atrophy or hole, epiretinal membranes and vitreous opacities. The most important step in cataract surgery in uveitis is adequate preoperative control of inflammation. Elimination of inflammation for at least three months before surgery is desirable. Manual small incision cataract surgery is a sutureless technique with which the nucleus is removed through a sclero-corneal tunnel incision. The most common setting for lensectomy with vitrectomy is in juvenile rheumatoid arthritis-associated uveitis. Pars plana vitrectomy with removal of all lens material through a posterior approach has been advocated as a means of preventing cyclitic membrane formation, by total elimination of the scaffolding upon which such membranes could form.
