Topical Ocular Hypotensive Medication and Lens Opacification: Evidence From the Ocular Hypertension Treatment Study

We noted an increased rate of cataract extraction and cataract/filtering surgery in the medication group as well as a borderline higher grade of posterior subcapsular opacification in the medication group on LOCS III readings. We found no evidence for a general effect of topical ocular hypotensive medication on lens opacification or visual function.
