Purpose: To evaluate the effect of learning curve on flap thickness (FT) outcome in femtosecond (FS) laser-assisted laser in situ keratomileusis (LASIK) operation for myopia performed with recently introduced LenSx dual platform using curved applanation cone.

Methods: Seventy eyes of 36 patients with myopia or myopic astigmatism operated with FS laser-assisted LASIK with recently introduced LenSx dual platform were evaluated in this retrospective study. Operations were divided into two groups: first 20 operations (20 eyes of 10 patients) and next 50 operations (50 eyes of 26 patients).

Purpose: To evaluate the clinical outcomes and quality of life following implantation of PanOptix toric intraocular lens (IOL) and to compare the outcomes following femtosecond laser assisted cataract surgery (FLACS) and standard cataract surgery (SCS).

Methods: This comparative retrospective study included 79 eyes of 55 patients underwent cataract or refractive lens exchange surgery between April 2017 and January 2020 in Bayindir Hospital and Kaskaloglu Eye Hospital. Corneal (CA) and refractive astigmatism (RA), uncorrected visual acuities for distant, intermediate, and near (UDVA, UIVA, and UNVA), low contrast distance visual acuity, rotational stability, defocus curves, photopic and mesopic contrast sensitivity (CS), visual function-14 (VF-14) test, presence of dysphotopsia, and need for spectacles were evaluated at postoperative third month.

Purpose: To evaluate the clinical outcomes following bilateral implantation of PanOptix intraocular lens (IOL).

Methods: This study included consecutive patients scheduled to undergo cataract or refractive lens exchange surgery between October 2017 and June 2018 at two centers. Manifest refraction, uncorrected distance visual acuity (UDVA), uncorrected intermediate visual acuity (UIVA, 60 cm) and uncorrected near visual acuity (UNVA, 40 cm), defocus curves, presence of dysphotopsia, need for spectacles, presence of posterior capsule opacification and visual function were evaluated at 6 months after surgery.

Purpose: To compare two different fragmentation patterns in femtosecond laser-assisted cataract surgery (FLACS) in terms of phaco values, postoperative endothelial cell count (ECC) and corneal thickness (CT).

Methods: This non-randomized, retrospective cross-sectional study included patients with senile cataract of grade 3 who underwent FLACS using the LenSx laser system. In Group 1 (32 eyes), lens fragmentation was created as a cross pattern.

Purpose: The purpose of this study was to compare the short-term changes in retina and choroidal tissue after femtosecond laser-assisted cataract surgery (FLACS) and standard phacoemulsification (PE) surgery.

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.

Purpose: To determine the safety of the Laser SoftFit™ patient interface by comparing intraoperative results with the contact interface of the LenSx® femtosecond laser platform (FSL).

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.
