Experiences with the Neodymium: YAG laser: interruption of anterior hyaloid membrane of the vitreous and cystoid macular edema.

Patients who needed posterior capsulectomy at different times following cataract surgery were treated with: The Meditec OPL3 mode-locked Nd:YAG laser; The LASAG Microruptor 2 Q-switched Nd:YAG laser. Random selection determined which instrument should be used for which patient. Further random selection determined the use of placebo with topical steroids vs. topical Indomethacin and topical steroid treatment. The results showed that there is a connection between the time the posterior capsulectomy is performed after cataract surgery, the number of applications used to interrupt the membrane, and the integrity of the anterior hyaloid membrane.
