Publication Metadata only Refractive precision in uncomplicated eyes with pseudoexfoliation: three-piece versus one-piece intraocular lens implantation(2021-01-01T00:00:00Z) Onur, Ismail Umut; Kirik, FURKAN; Yigit, Fadime Ulviye; Vural, Asli Deger; Cavusoglu, Ercan; Evcimen, Yusuf; KIRIK, FURKANPurpose: To evaluate the refractive precision of three-piece versus one-piece intraocular lenses (IOLs) in eyes with pseudoexfoliation (PXF) and changes in anterior chamber depth (ACD) following cataract surgery.Publication Metadata only Correlation with Schirmer test and break up time of tear osmolarity measurement in dry eye syndrome patients Kuru göz sendromlu hastalarda gözyaşi osmolarite ölçümünün schirmer testi ve gözyaşi kirilma zamani ile ilişkisi(2013-01-01T00:00:00Z) Yiǧit, Ulviye; Kirik, FURKAN; Evcimen, Yusuf; Aǧaçhan, Ahmet; KIRIK, FURKANObjective: To evaluate the correlation with Schirmer Test and Break up Time (BUT) of tear osmolarity measurement in dry eyes syndrome (DES) patients. Material and Methods: New diagnosed 30 dry eye patients and 30 healthy voluntary persons of similar age and gender included prospectively in this study. In addition to the full ophthalmic examination, Schirmer Test and BUT test were performed to all participants. Tear osmolarity measurements have been done after pre-examination but in different day, with TearLab Osmolarity System (TearLab Corporation, San Diego, CA, USA). The results have been evaluated statistically. Results: No statistically significant difference was found between mean age, gender of DES and control groups (p<0.05). The mean measurement of Schirmer Test and BUT of DES group were statistically significantly lower than control group (p=0.0001). The mean measurement of tear osmolarity were statistically significantly higher than control group (p=0.0001). When the results were evaluated in DES group, Schirmer test value were found positively correlated with BUT value (r=0.626, p=0.0001). Between Schirmer test value and the measurement of tear osmolarity, there was a negative correlation (r=-0.414 p=0.008). Negative correlation was also observed between BUT and the measurement of tear osmolarity (r=-0.378 p=0.015). Conclusion: It has been concluded that there is no difference among tear osmolarity, Shirmer and BUT tests in diagnosis of DES.Publication Metadata only Daytime variations of tear osmolarity measurement in dry eye patients Kuru göz hastalari{dotless}nda gözyaşi{dotless} osmolarite ölçümünün gün İçi deǧişiklikleri(2013-01-01T00:00:00Z) Yiǧit, Ulviye; Evcimen, Yusuf; Kirik, FURKAN; Aǧaçhan, Ahmet; KIRIK, FURKANPurpose: We have targeted primarily to show the variations of tear osmolarity during the daytime period in subjects with dry eyes and non-dry eyes and, secondarily, to evaluate the relationship of these variations with Schirmer-s test and break-up time (BUT). Material and Method: Twenty newly diagnosed dry eye patients and 20 healthy voluntary subjects with similar age and gender were included in this prospective study. In addition to the full ophthalmic examination, Schirmer-s test and BUT test were applied to all participants. Tear osmolarity measurements were done after pre-examination but in different day. The measurements were registered with TearLab Osmolarity System (TearLab Corporation, San Diego, CA, USA) every 3 hours within 8:00 AM and 5:00 PM. The results were evaluated statistically. Results: No statistically significant difference was found between the mean age and gender of dry eye syndrome (DES) and control groups (p>0.05). The mean measurements of Schirmer-s test and BUT in the DES group were statistically significantly lower than those in the control group (p=0.0001). The mean measurements of tear osmolarity at 8:00 AM, 11:00 AM, 2:00 PM, and 5:00 PM in the DES group were statistically significantly higher than those in the control group (p=0.001, p=0.0001). No statistically significant difference in tear osmolarity at 8:00 AM, 11: 00 AM, 2:00 PM, and 5:00 PM was found between the groups, and within DES and control groups (p>0.05). Discussion: We did not determine significant change in daytime variations of the tear osmolarity in dry eye patients and healthy subjects. As a secondary result, we can conclude that there is no difference among tear osmolarity, Shirmer-s and BUT tests in the diagnosis of DES.Publication Metadata only Comparison of Two Laser Capsulotomy Techniques: Cruciate Versus Circular(2014-05-01T00:00:00Z) Kara, Necip; Evcimen, Yusuf; Kirik, FURKAN; Agachan, Ahmet; Yigit, Fadime Ulviye; KIRIK, FURKANPurpose: To compare the safety and efficacy of two Nd: YAG laser capsulotomy techniques. Methods: In this prospective comparative interventional case series, 60 eyes of 57 patients with posterior capsular opacification were enrolled. Thirty eyes were selected to undergo a cruciate capsulotomy (Cross group) and the other 30 eyes were selected to undergo a circular capsulotomy (Circular group). Main outcome measures were best-corrected visual acuity (BCVA), intraocular pressure (IOP), amount of energy used, mean macular thickness (MMT), and floater symptoms. Results: The amount of energy used was significantly higher in the Circular group than in the Cross group (p 0.05). The number of patients with floater symptoms was significantly higher in the Circular group than in the Cross group at one week and one month (p < 0.05). Conclusion: Both the cross-like and circular Nd:YAG laser capsulotomy techniques induce similar visual and IOP changes. The circular technique is associated with a higher amount of energy used, more floater symptoms, and has a greater effect on macular thickness at one day after laser capsulotomy.
