Two center trial with medical university Graz: Influence of combined vitrectomy plus cataract surgery on postoperative intraocular lens position: a prospective bilateral comparison

Even with modern measurements techniques, such as optical biometry, and using the latest generation of IOL power calculation formulae, there is a relevant unpredictability of the post-operative manifest refractive outcome. However, most studies are focusing on cataract surgery and there is little literature concerning the prediction of the post-operative IOL position in combined cataract surgery with vitrectomy. Combination of cataract operation with vitrectomy for vitreomacular diseases has the advantage of better visualization of the posterior pole during the operation in eyes with a (sub)clinical cataract. Aim of this study is to assess the influence of combined vitrectomy and cataract surgery on the post-operative IOL position in comparison to cataract surgery without additional surgery.
