Extracapsular cataract extraction and posterior-lip sclerectomy with viscoelastic

A review of 15 cases suggests that posterior-lip sclerectomy can be performed safely with extracapsular cataract extraction (ECCE) and posterior chamber lens implantation. The anterior chamber was filled with viscoelastic at the end of each procedure; no case required reoperation for shallow chamber or hypotony. The mean intraocular pressure after 1 year was 12.1 mm Hg. The astigmatism induced by the triple procedure did not differ significantly from that caused by ECCE alone during the initial 2 postoperative years. A new mathematical model that describes the change over time of postoperative astigmatism associated with these procedures is described.
