[Secondary cataract and IOL type and the shape of its optic part].

Although cortical remains are purged from the capsule sac by special techniques and better IOL models are used for implantation, opacification of the posterior capsule (OPC) persists to be one of the most frequent complications in modern cataract surgery. The frequency rate of OPC depends on used evaluation criteria. A total of 165 eyes were examined after cataract extraction for OPC.

[Clinical experience with the use of improved-design monolithic intraocular lens].

A monolithic intraocular lens (IOL) design is described, made of with a total diameter of 8.5-9.0 mm.

[Anterior capsulectomy in extracapsular cataract extraction].

Extracapsular cataract extraction involves several stages, one of which is anterior capsulectomy. Up to present anterior capsulectomy was performed before removal of the lens sac contents in the majority of cases, this ruling out the use of the anterior capsule of the lens as a posterior corneal epithelium protector. The author has developed two types of scissors that permit resection of the anterior capsule of the lens before removal of the lens mass.
