118Rad 530. Medical Sciences, 44(2017) :103-120International Scientific Symposium What’s New in Refractive Eye Surgery the central flap thickness 94,04±3,20µm (P<.001). Flaps in femtosecond group 3 had the least difference between the mean peripheral 108,12±17µm and the central flap thickness 105±15,5µm (P<0.68). meridian flap uniformity measured at 10 measure-ment points at 90- and 180- degrees were uniform and regular for each femtosec-ond device. The flap thickness predictability was similar in all femtosecond groups (P=0.312). Conclusions: Flap morphology differed according to the system used. Although the central flap thickness created by the Ziemer LDV was less than that created by the Intralase and VisuMax, measurements of 3 femtosecond lasers were close to the intended thickness. Keywords: femtosecond laser; LASIK; flap thickness; myopia.PACHO  SURGERY  IN  REDUCTION  OF  POST--KERATOPLASTY  REFRACTIVE  ERRORAdi Pašalić, Adrijana Dukić, Iva DekarisSpecial Eye Hospital “Svjetlost”, Department of Ophthalmology, School of Medicine, University of Rijeka, Zagreb, CroatiaPurpose: To evaluate visual improvement in patients undergoing Phaco surgery under the corneal graft and to evaluate possible negative impact of cataract surgery for corneal graft survival.Methods: Prospective, consecutive, interventional case series. The study ana-lysed post-keratoplasty eyes after cataract surgery (Phaco) and spherical-error cor-recting intraocular lens (IOL) implantation. Incision site was made at the steepest axis determined by corneal topography (Pentacam); additional limbal relaxing inci-sion (LRI) was made as needed. All surgeries were done after the suture removal, in patients aged 20 to 75 years. Uncorrected distance visual acuity (UDVA), best cor-rected visual acuity (bCVA), change in refractive error, graft clarity, endothelial cell density loss (ECD) and adverse events were recorded. The mean follow-up was 8 ± 3 months.Results. Twenty-seven eyes with cataract formation after PK were included. The mean age at cataract surgery was 56 years ±13 years (SD). The mean refractive spheri-cal equivalent decreased significantly, from -1.98 ± D to 0.38 ± D (P<0,05). The mean refractive astigmatism also decreased significantly, from -5.34 ± D to -1.86 ± D (P<.0,1). There was a significant improvement in the mean uncorrected distance visual acuity 119Rad 530. Medical Sciences, 44(2017) :103-120International Scientific Symposium What’s New in Refractive Eye Surgery (UDVA), from 0.24 ± 0.12 to 0.48 ±0.08 (P<0,05) and in the mean corrected distance visual acuity (CDVA), from 0.6 ±0.2 to 0.8± 0.1 (P<0,05) from preoperatively to the last follow-up (both P<0,05). At 1 year after Phaco, the uDVA was 20/40 or better in 37% of eyes and CDVA was 20/25 in 57% of eyes. Vision remained stable till 5 post-operative years, with uDVA of 20/40 or better in 34% of eyes and CDVA of 20/25 in 55% of eyes. ECD did not change significantly; from 2049 ±370 preoperatively to 1987 ±513 cells/mm2 post-Phaco. During 5 years of ECD loss follow-up we found no significant dif-ference in ECD loss between PK eyes submitted to Phaco or without Phaco.Conclusion. Phaco after PK corrected most of the preoperative refractive error, bringing patients to significantly better uDVA and CDVA compared to their vision prior to cataract formation. Since Phaco surgery in a soft post-PK cataracts did not induce any significant ECD loss or changes in graft clarity, cataract may nowadays be considered as a relative post-PK complication.Keywords: Phaco; cataract; keratoplasty; refractive error; corneal graft.REFRACTIVE  OUTCOME  OF  KERATOPLASTY  OVER  MULTIFOCAL  IOLmateja Končarević, Adrijana Dukić, Iva DekarisSpecial Eye Hospital “Svjetlost”, Department of Ophthalmology, School of Medicine, University of Rijeka, Zagreb, CroatiaPurpose: To present patient with implanted multifocal intraocular lenses (MFI-OL) who underwent corneal transplantation for pseudophakic bullous keratopathy (PbK). To present a patient with implanted multifocal intraocular lenses (MFIOL) who underwent two different techniques of corneal transplantation for pseudopha-kic bullous keratopathy (PbK).Methods: Due to development of bullous keratopathy after an uneventful cata-ract surgery, a 64-year-old female patient underwent penetrating keratoplasty (PK) on her right eye, and two years after UT-DSAEK (Ultra Thin - Descemet’s Stripping Automated Endothelial Keratoplasty) on her left eye. During a 2 year follow up we compared visual recovery, best corrected visual acuity (bCVA), postoperative astig-matism, endothelial cell loss, and graft outcome.Results: The eye that underwent uT-DSAEK procedure showed better postop-erative bCVA, both in quantity and speed of recovery as compared to the other eye that underwent PK. UT-DSAEK eye achieved bCVA of 0.95 in less than 1 month
