Treatment of Cataract
Surgical removal of the cataract Placement of an intraocular lens Frequent refractions and corrective lens prescription changes may help maintain useful vision during cataract development. Rarely, long-term pupillary dilation (withphenylephrine2.5% every 4 to 8 hours) is helpful for small centrally located cataracts. Indirect lighting while reading minimizes pupillary constriction and may optimize vision for close tasks. Usual indications for surgery include the following: Best vision obtained with glasses is worse than 20/40 (<6/12), or vision is significantly decreased under glare conditions (eg, oblique lighting while trying to read a chart) in a patient with bothersome halos or starbursts. Patients sense that vision is limiting (eg, by preventing activities of daily living such as driving, reading, hobbies, and occupational activities). Vision could potentially be meaningfully improved if the cataract is removed (ie, a significant portion of the vision loss must be caused by the cataract). Far less common indications include cataracts that cause Overview of Glaucoma or that obscure the fundus in patients who need periodic fundus examinations for management of diseases such as
