The control group (CG) included 12 people (18 eyes) who had no ocular disease other than refractive errors. Those with a visual acuity level less than 20/25 were not included in the study. Contrast sensitivity levels and light threshold values of the central retina were measured; scanning-slit corneal topography-pachymetry and aberrometric analysis were performed. Results: There were no statistical difference in terms of age (32.55 years Ϯ 9.25 (SD) in PG, 36.75 Ϯ 5.85 years in CG; P ϭ .53), cylinder power in plus form (2.60 Ϯ 1.25 diopter (D) in PG, 2.79 D Ϯ 2.51 D in CG; P ϭ .88), and spherical equivalent of refractive errors (Ϫ3.66 Ϯ 3.57 D in PG, Ϫ5.52 Ϯ 3.37 D in CG; P ϭ .29) between the PG and CG. Cambridge low-contrast grating scores were 96.5 Ϯ 41.1 in grafted eyes and 148 Ϯ 27.7 in CG (P ϭ .004). Central retinal light sensitivity was measured as 29.91 Ϯ 2.39 db in PG and 33.08 Ϯ 1.56 db in CG (P ϭ .001). In corneal topographic analysis, mean kappa intercept was 0.69 Ϯ 0.37 mm in PG and 0.55 Ϯ 0.24 mm in CG (P ϭ .20). Lower-order Zernike root mean squares (RMS) were 7.30 Ϯ 3.89 m for PG and 8.58 Ϯ 3.46 m for CG (P ϭ .37). However, higher-order Zernike RMS were 2.15 Ϯ 0.78 in PG and 0.38 Ϯ 0.10 in CG, which is a statistically significant difference (PϽ.001). Conclusions: Even though the clinically successful PKP patients have correctable amount of spherocylindrical refractive errors with spectacle lenses, they still have reduced visual quality because of the significantly high amount of higherorder aberrations when compared with naturally occurring refractive errors.

Ge reç ve Yön tem: 2013 Mart-2013 Mayıs tarihleri arasında femtosaniye laser yardımlı katarakt ve RLD ameliyatı yapılan 29 hastanın 50 gözü çalışmaya alındı. Tüm hastalara Femtosaniye laser cihazı (LenSx ® , Alcon Inc.) ile komple prosedür (kapsülotomi, lens fragmantasyonu ve korneal kesiler) uygulandı. Ameliyatlar fakoemülsifikasyon ve göz içi lensi yerleştirilerek tamamlandı. İntraoperatif komplikasyonlar retrospektif olarak hasta dosyalarından ve ameliyat videolarından değerlendirildi. Bulgular: Hastaların yaş ortalaması 63,8±11,7 (SD) yıl idi. Vakum kaybı ya da anterior kapsül yırtığı hiçbir gözde oluşmadı. On bir gözde (%22) küçük ön kapsül etiketleri oldu. Yedi gözde (%14) serbest kapsülotomi, 40 gözde (%60) mikroadezyonlarla birlikte parsiyel tamamlanmış kapsüloreksis ve 3 gözde (%6) inkomplet kapsüloreksis izlendi. Bir gözde (%2) intrakapsüler basınç artışına bağlı arka kapsül rüptürü gelişti. Korneal kesiler 8 gözde (%16) kullanılmak istenmedi, 4 gözde (%8) tamamlanamadı. Miyozis 20 gözde (%40) meydana geldi. Vizyon kaybı ya da nükleus drop gözlenmedi. Sonuç: Femtosaniye laserlerin katarakt ve RLD cerrahisinde kullanımı güvenlidir. Komplikasyonlara bağlı görme kaybı gelişmemiştir.

Methods: In all, 25 eyes undergoing FLACS and 27 eyes undergoing PE surgery were included in this nonrandomized, retrospective, cross-sectional study. Central retinal thickness (CRT) and choroidal thickness (CT) were measured pre-and postoperatively (at day 1, 1 week later, and after 1 month) with spectral domain optical coherence tomography (OCT) in all patients and were compared. For group comparisons, chi-square test and independent t-test were used. Postoperative values were compared to the baseline using a paired t-test. The magnitude of the change from baseline to the peak was analyzed by multiple regression models in an attempt to explain possible influence variables. Results: Pre and postoperative CRT measurements were similar in both groups. The mean subfoveal CT at day 1, after 1 week, and 1 month were significantly higher than baseline CT measurements in the PE group. Conclusion: FLACS might have an advantage in regard to postoperative choroidal changes.

Methods In this nonrandomized, consecutive case series, 50 eyes underwent femtosecond laser-assisted cataract surgery (FLACS) using the LenSx® laser platform (group 1); FLACS was performed in another 50 eyes, using the Laser SoftFit™ patient interface (group 2). Intraoperative complications (corneal folds) and surgical results (incomplete and free capsulotomies, incomplete phacofragmentation, and unopened incisions) were compared. Results Corneal folds and incomplete capsulotomies were less common (p = 0.0001 for both) and free-floating capsulotomies were more frequent (p = 0.0001) with the Laser SoftFit™ patient interface. Incomplete phacofragmentation and unopened incision exhibited similar rates in both groups (p = 0.436 and 0.204, respectively). Conclusions Using the Laser SoftFit™ patient interface...

Ege University Hospital, Eye Department, Izmir, Turkey. Forty-three patients of either sex, aged 49 years, or older, were included in the study. Clear corneal incision, circular curvilinear capsulorhexis, phacoemulsification and implantation of the Medevec VS 2 UV(TM) mini-loop silicone plate lenses using the injector-cartridge system was performed in all cases. The mean outcome measures were ease of implantation, intraoperative and postoperative complications, postoperative centration and visual acuity. The mean follow-up was 10.2 months (range 8-11 months). Twenty-two lenses (44 required two or more manoeuvers). In 6 cases, the lens was implanted into a bag with torn anterior capsule and in 3 patients (6 implanted into the sulcus because of a torn posterior capsule during phacoemulsification). Best corrected visual acuity was &...

These foreign bodies were removed by a closed chamber technique using a simple loop. The loop was created by a 22-gauge intravenous cannula and a 7-0 polypropylene suture. Retained cilia in one patient and metallic foreign bodies in two patients were removed using this intraocular "lasso." Sutures were not placed at the incision sites at the end of the surgery. This is an inexpensive and easy to prepare technique that introduces minimal surgical trauma. In addition, two hands are not needed for loop manipulation. This technique may be an excellent alternative for removal of small intraocular foreign bodies.

The purpose of this study was to evaluate the early results in our patients. The Technolas Keracor 116 excimer utilizes a scanning beam to correct myopic astigmatism. Following the correction of the astigmatic error, spherical myopic component is then treated. Twenty-eight eyes with myopic astigmatism were treated utilizing a 4 x 12 mm ablation zone for astigmatism and 4.5 mm to 6.6 mm transition zone for the spherical component at the same session. The mean preoperative spherical equivalent refraction was -4.87 +/- 3.48 diopters (D) (range: -1.00 to -14.25) and the mean preoperative astigmatic error was -2.53 +/- 1.49 D (range: -1.00 to -6.00 D) All eyes received dexamethasone eye drops for 3 months. At 6 months, the mean spherical equivalent refraction was +0.23 D (range +1.38 to -1.50 D), the mean postoperative refractive cylinder was -0.16 +/- 0.99 D (range: +1.50 to -2.00 D) and 78% of the eyes...

Preoperative refractive errors (spherical equivalent) ranged between -1.75 diopters (D) and -20.00 D (mean: -7.19 +/- 3.73). A single ablation zone ranging from 4.5 mm to 6 mm was used. In all eyes except for those with myopia over -15 D, emmetropia was a goal. Postoperatively patients used fluoromethalone drops for 1 month. Treated eyes were divided into four groups based on preoperative myopia. Group 1 contained 15 eyes with myopia less than -3 D (93% were within +/- 1 D postoperatively). In Group 2 there were 53 eyes with preoperative myopia between -3.25 D and -6.00 D (64.1% were within +/- 1 D postoperatively). Group 3 consisted of 53 eyes with preoperative myopia between -6.25 D and -10.00 D (41.5% were within +/- D postoperatively). Group 4 contained 36 eyes with myopia over -10.00 D (13.8% were...

The optical component is embedded in a carrying device designed as an intraocular lens that is implanted after cataract surgery. In this study, we report findings on an IMT that was explanted because of aqueous infiltration into its optic and describe the configuration of this device and the surgical technique required for its implantation. The patient, a 75-year-old male with bilateral cataract and nonexudative ARMD, underwent phacoemulsification with implantation of an IMT in the right eye. The rigid device, weighing 46.1 mg in aqueous, has an overall diameter of 13.5 mm and requires implantation through a large limbal incision. It is fixated at the 6 to 12 o'clock meridian. Follow-up examination revealed the presence of numerous droplets inside the IMT optic. The device was explanted and sent to our c...
