Lens Position Parameters as Predictors of Intraocular Pressure Reduction After Cataract Surgery in Glaucomatous Versus Nonglaucomatous Eyes.
Pressure lowering from cataract surgery better in eyes with shallow anterior chambers
Preoperative lens position is useful a parameter to consider in the management managing glaucoma patients with cataracts, the results of a prospective study suggest. In a series of 76 eyes of 57 primary open-angle glaucoma with and 97 eyes of 73 patients without primary open-angle glaucoma, researchers compared the preoperative lens position measured by optical biometry with the change of IOP from preoperatively to four months after cataract surgery. They found that eyes with shallower lens positions prior to cataract surgery were likely to have greater reductions in intraocular pressure than those with deeper lens positions, whether or not they had glaucoma. The study’s authors note that lens position is a simple, easily calculable, accurate, and widely available parameter.
