Position OF DIACARAB ACETAZOLAMIDE AND TIMOLOL PREMEDICATION Throughout PREVENTION OF CATARACT PHACOEMULSIFICATION Difficulties

RESULTS A total of 80 eyes of 40 patients were evaluated in this study. Although monocular and binocular uncorrected and corrected distance and near visual acuities were similar between groups, monocular and binocular UIVA were significantly higher in the Eyhance group. There were no statistically significant differences between the 2 groups in terms of photopic contrast sensitivity, OSI, MTF cutoff, Strehl ratio, and glare and halo perception. The ICB00 IOL provided better spectacle independence than the ZCB00 IOL for intermediate distance. CONCLUSIONS In patients without ocular comorbidities, the Eyhance ICB00 IOL provided better UIVA and higher intermediate spectacle independence without impairment of far vision and visual quality, compared with the ZCB00 IOL.PURPOSE To compare the long-term refractive effects of small incision lenticule extraction (SMILE) and femtosecond laser-assisted laser in situ keratomileusis (FS-LASIK) for correction of high myopia and astigmatism. SETTING The Eye and ENT Hospital of Fudan University DESIGN Retrospective case series. METHODS This study included 121 patients (121 eyes 75 in SMILE group and 46 in FS-LASIK group) who underwent SMILE or FS-LASIK for high myopia. Subgroup analyses of high myopia ( less then -9.00 diopters [D]) and extremely high myopia (≥ -9.00 D). The main outcome measure was refractive predictability compared between SMILE and FS-LASIK. Secondary outcomes includeded efficacy, safety, and residual astigmatism. RESULTS We found no differences in terms of refractive predictability between SMILE and FS-LASIK in eyes with high myopia 56% versus 58.7% achieved ± 0.5 D of attempted correction (P=0.771), and 81.3% versus 76.1% achieved ± 1.0 D of attempted correction (P=0.489), respectively. Efficacy indices of the SMILE and FS-LASIK groups were 1.02 ± 0.24 and 1.03 ± 0.24 (P=0.742); safety indices were 1.23 ± 0.22 and 1.20 ± 0.24 (P=0.324), respectively. LogMAR UDVA and spherical equivalent in the high myopia subgroup were better than those in the extremely high myopia subgroup after both SMILE and FS-LASIK (P less then 0.01). CONCLUSIONS SMILE and FS-LASIK were both effective in correcting high myopia and myopic astigmatism. However, both techniques may require further nomogram adjustments when treating eyes with extremely high myopia.PURPOSE To evaluate axial length (AL) measurements and detection rates using a swept-source optical coherence tomography (SS-OCT) biometer (OA-2000) compared with the IOLMaster, LENSTAR, and ultrasound (US) measurements in eyes with vitreous hemorrhage. SETTING Eye Hospital of Wenzhou Medical University, China. DESIGN Comparative evaluation of a diagnostic test or technology. METHODS Patients were adults with vitreous hemorrhage in one or both eyes. Lens Opacities Classification System III was used to determine they type and severity of cataract and the Forrester system was used to classify the grade of vitreous hemorrhage. The AL measurement was taken with the OA-2000, IOLMaster (v5.4), and LENSTAR (v2.1), and with US (Axis-II). The Bland-Altman test was used to assess the agreement between devices. RESULTS Forty eyes were scanned with each of the 4 biometers. For Forrester grade III, the detection rate was 100%, 41.7%, and 41.7% with the OA-2000, IOLMaster, and LENSTAR, respectively. For Forrester grades I and II, the detection rate was 46.4%, 3.57%, and 3.57% with the OA-2000, IOLMaster, and LENSTAR, respectively. The detection rate with US was 100% for all grades. The Bland-Altman limits of agreement between the 4 biometers indicated an excellent agreement OA-2000 vs IOLMaster (95% limits of agreement -0.15 to 0.05 mm), OA-2000 vs LENSTAR (-0.04 to 0.12 mm), and OA-2000 vs US (-0.3 to 0.56 mm). CONCLUSIONS In vitreous hemorrhage, the detection rate with the SS-OCT OA-2000 biometer was better than that with the IOLMaster and LENSTAR. In cases in which all biometers were able to acquire an AL measurement an excellent agreement was found.PURPOSE To evaluate the outcomes of 4 low laser energy levels after small-incision lenticule extraction (SMILE) surgery. SETTING Zhongshan Ophthalmic Center, Guangzhou, China. DESIGN Prospective randomized clinical trial. METHODS This study evaluated consecutive patients who had SMILE to correct myopia or myopia with astigmatism. Eyes were placed into groups based on the laser energy used during surgery (ie, 105 nJ, 110 nJ, 115 nJ, or 120 nJ). All patients had a thorough ophthalmic examination preoperative and at 4 timepoints over 3 months postoperatively. Black areas and surface regularity of the extracted lenticules were observed and evaluated qualitatively and quantitatively. RESULTS The study comprised 124 eyes of 62 patients (40 women, 22 men), with 31 eyes in each laser energy group. The incidence of black areas was 45.16% (14 of 31 eyes), 12.90% (4 of 31 eyes), 16.13% (5 of 31 eyes), and 12.90% (4 of 31 eyes) for 105 nJ, 110 nJ, 115 nJ, and 120 nJ, respectively. The mean time for lenticule creation was the longest in the 105 nJ group (P = .015). The greatest increase in corneal thickness postoperatively occurred with 105 nJ (P less then .05). Regression was highest in the 105 nJ group at 3 months (P less then .01). Selleckchem Scriptaid However, corneal horizontal coma (C8) was lowest in the 105 nJ group at 1 week (P = .032). The lenticular surface in the 110 nJ group was the smoothest (P = .011). All contrast sensitivity values varied with time and recovered to preoperative levels by 1 week or 1 month. In all eyes, the uncorrected distance visual acuity and corrected distance visual acuity were good, with no statistically significant differences between the 4 energy groups. CONCLUSIONS The 105 nJ group, in which the lowest energy was used, had the highest risk for black areas, serious postoperative corneal edema, and a significant healing response.PURPOSE To compare the visual acuity and satisfaction outcomes of two different concepts of enhanced depth of focus intraocular lenses (EDOF IOLs). SETTING University Eye Hospital Bochum, Germany DESIGN Prospective randomized comparative clinical trial METHODS This study included a sample of 76 eyes of 38 patients undergoing cataract surgery with the implantation of two different EDOF concepts. In the first group (IC-8 group) a monofocal 1-piece Tecnis Z B00 IOL (Johnson & Johnson Vision) was implanted in the dominant eye and an IC-8 IOL (AcuFocus) was implanted in the non-dominant eye. In the second group (Symfony group) a Tecnis Symfony IOL (Johnson & Johnson Vision) was implanted in both eyes. The target refraction of the dominat eye was emmetropia and slight myopia (mini-monovision; -0.75 D) in the non-dominant eye. Visual and refractive outcomes and patient satisfaction rates were evaluated 3 months after surgery. RESULTS In both groups no intra- or postoperative complications occurred. The target refraction was reached in both groups without statistical significant differences.
