The clinical results confirm the theoretical preclinical calculations that the spherical aberration of the eye after cataract surgery can be eliminated by modifying the anterior surface of the IOL. The Tecnis Z9000 lens compensates for the positive spherical aberration in older eyes. This leads to a significant improvement, particularly in contrast sensitivity and mesopic visual quality.

These results demonstrate the therapeutic effect of surgical AV decompression in BRVO. Additional removal of the ILM seems to improve the functional results. Further experience may answer some open questions.

Pars-plana vitrectomy with ILM peeling reduced macular oedema in most cases. In contrast, visual acuity improved significantly in 43% of the treated eyes only. The discrepancy between anatomical and functional results of ILM removal in chronic diabetic macular oedema is likely to be caused by structural changes of the macula due to long-standing oedema.

A significant difference was observed between the two MIOL in improved near visual acuity of the Acri. Twin MIOL (0.8 vs 0.4). Most of the patients described dysphotic phenomena, which were somewhat different for both MIOL, but expressed general satisfaction except for one patient. Concerning contrast sensitivity both MIOL were significantly inferior to data published for an aspherical monofocal IOL.

Our results with surgical decompression of branch retinal vein occlusions demonstrate the therapeutical effect of surgical AV-decompression in BRVO. Further experience is necessary before some open questions can be answered.
