About

The aim of the study is to gain more insight into the potential impact of a vitrectomy (removal of the vitreous) on postoperative effective position of the intraocular lens (IOL). Moreover, this study can provide very useful information for the optimal lens calculation in patients undergoing lens extraction with IOL implantation (whether or not combined with a vitrectomy) should undergo.

Full description

• Comparison ELP post phaco VTX (pucker / floaters) versus post phaco and use this information to develop a customized IOL calculation for eyes undergoing phacoVTX.
• Evidence for recording lens thickness (LT) parameter in the IOL strength calculation in KWS (in the calculation of the ELP in the light of the Olsen formula, using the C-constant) in order to be able to make an even more accurate prediction of the post-operative diopter target of the patient.
