Abstract Details


To evaluate refractive outcomes in patients who underwent combined PDEK and cataract surgery in one single procedure and determine eventual refractive shift.


Department of Ophthalmology, University Hospital Kralovske Vinohrady, Prague, Czech Republic


The retrospective study comprised 20 eyes of 19 patients who underwent PDEK and phacoemulsification with implantation of hydrophobic monofocal IOL in one single procedure. All patients had corneal endothelial dystrophy and presence of cataract. Biometry and IOL power calculation was performed by the IOLMaster 500 (Carl Zeiss) using SRK-T formula. Supposing hyperopic shift, IOL was selected to mild myopia. Best-corrected distance visual acuity (BCDVA) and spherical equivalent (SE) were evaluated preoperatively and 3 and 6 months postoperatively. The postoperative spherical equivalent was compared with the intended target refraction.


The mean BCDVA increased from 0,48 �Â�± 0,20 preoperatively to 0,76 �Â�± 0,19 at 3 months and 0,84 �Â�± 0,16 at 6 months postoperatively. The mean target refraction in IOL power calculation was -0,60 �Â�± 0,16 D. The mean preoperative SE was �,41 �Â�± 2,16 D, -0,20 �Â�± 1,09 D 3 months after surgery and -0,21 �Â�± 0,86 D 6 months after surgery. However, 4 eyes (20%) had final hyperopic refraction.


In our study we confirmed hyperopic shift of refraction in patients after combined procedure PDEK and cataract surgery. In our group of patients it seems that optimal refractive results could be achieved by selecting intraocular lens aimed to -1,0 D.
