    Effect of Corneal Incision Enlargement on Surgically Induced Astigmatism in Biaxial Microincision Cataract Surgery
    (TURKISH OPHTHALMOLOGICAL SOC, 2016) Tetikoglu, Mehmet; Yeter, Celal; Helvacioglu, Firat; Aktas, Serdar; Sagdik, Haci Murat; Ozcura, Fatih
    Objectives: To evaluate surgically induced astigmatism (SIA) in biaxial microincision cataract surgery with enlargement of one corneal incision during intraocular lens implantation (IOL). Materials and Methods: Data from 683 eyes with cataract that underwent biaxial microincision cataract surgery and IOL were retrospectively analyzed. The operated eyes were divided into 4 groups defined by final corneal incision length after IOL implantation. There were 83 eyes with 1.6 mm corneal incisions (group 1) and 200 eyes in each of the 2, 2.4, and 2.8 mm corneal incision groups (groups 2, 3 and 4, respectively). SIA was assessed using preoperative and postoperative keratometric values at one month. Results: The mean magnitude of SIA was 0.83+/-0.4 D in group 1, 0.93+/-0.5 D in group 2, 1.03+/-0.6 D in group 3 and 1.04+/-0.7 D in group 4. The SIA showed statistically significant differences between the four groups (p=0.05). Pairwise group comparisons revealed significant differences between groups 1 and 3 and groups 1 and 4 (p=0.005). Conclusion: Biaxial microincision cataract surgery with an incision size of 1.6 mm resulted in the least SIA. Enlargement of the corneal incision beyond 2.0 mm during IOL implantation led to significant increases in SIA. We believe that with the development and dissemination of IOLs which can be inserted through small corneal incisions, biaxial microincision cataract surgery will be the best choice to prevent SIA and increase visual acuity.

    Effects of Hyperandrogenism on Tear Function and Tear Drainage in Patients with Polycystic Ovary Syndrome
    (SCI PRINTERS & PUBL INC, 2011) Coksuer, Hakan; Ozcura, Fatih; Oghan, Fatih; Haliloglu, Berna; Karatas, Serap
    OBJECTIVE: Polycys tic ovary syndrome (PCOS) is an endocrinopathy characterized by chronic anovulation and hyperandrogenism. Hormonal changes can affect ocular surface and tear functions. We evaluated dry eye symptoms, clinical tear film alterations, and tear clearance in patients with PCOS. STUDY DESIGN: Thirty-five women with PCOS and 22 healthy individuals were enrolled in the study. An ocular surface disease index (OSDI) questionnaire was administered, and after the routine ophthalmologic examination tear film breakup time (TB UT) and Schirmer tests were performed. Tear clearance was assessed via fluorescein dye disappearance test (FDDT). RESULTS: No difference was observed in Schirmer test between the groups, however OSDI scores were significantly higher (p=0.01) and TBUT was significantly lower (p=0.01) in PCOS patients than in the control women. FDDTs were not different between the PCOS and control subjects. CONCLUSION: Our findings suggest that patients diagnosed with PCOS should be advised to obtain an ophthalmic examination, especially for dry eye. (J Reprod Med 2011;56:65-70)
