Prevalence of laser refractive surgery among ophthalmologists in Saudi Arabia

ConclusionExcimer laser vision correction among ophthalmologists in Saudi is much higher than the market penetration in the general population reported in other countries. Most of the ophthalmologists who underwent the procedure were satisfied with the outcome.

Purpose: Evaluation of spherical component (SC), regular astigmatism (RA), and irregular astigmatism (IA, ie, Asymmetry and Irregularities) 3 years after small incision lenticule extraction (SMILE) and comparison to femtosecond laser-assisted laser in situ keratomileusis (FS-LASIK). Methods: Thirty-two eyes of 21 patients who underwent SMILE for myopia and astigmatism were compared with 32 eyes of 21 patients treated with FS-LASIK. Scheimpflug images were obtained preoperatively and 3 years postoperatively. Fourier analysis of keratometric-derived parameters (SC, RA, Asymmetry, and Irregularities) of the anterior, pos...

Conclusions: Our findings suggest that femto-LASIK on eyes with prior FLEK is safe and effective in improving visual acuity and reducing residual astigmatism. PMID: 31559093 [PubMed]

Authors: Breyer DRH, Beckers L, Hagen P, Kaymak H, Klabe K, Auffarth GU, Kretz FTA Abstract AIM: Our aim was to retrospectively compare ReLEx Smile to femtosecondlaser-assisted LASIK (FsLASIK, femto-LASIK) in terms of safety, efficacy, stability as well as intraoperative complications. Comparable studies only show the results over the course of 3 years, making our data the first to examine longer term results. MATERIALS/METHODS: To accomplish this, we compared 404 eyes after FsLASIK (Mel 80, Carl Zeiss Meditec) and 1192 eyes after ReLEx SMILE (VisuMax, Carl Zeiss Meditec). We collected patients' data at 6 month...

derli A Abstract PURPOSE: To evaluate the postoperative high-order aberration differences of femto-LASIK surgery in 6.5 and 7 mm optic zones. PATIENTS AND METHODS: We retrospectively reviewed 80 eyes of 40 patients with myopia or myopia with astigmatism who underwent femtosecond LASIK surgery. Q values, z3, 3 (h. trefoil), z3, -3 (v. trefoil), z3, 1 (h. coma), z3, -1 (vertical coma), z4, 0 (spherical aberration), z5, -1 (second other v. coma), aberration coefficients were evaluated 3 months after surgery. Central corneal thicknesses, intraocular pressures, patient ages and genders, optical zone ...

Authors: Zhao LQ, Li LM, Liu J, Li P Abstract Purpose: To assess the efficacy of applying bandage contact lens (BCL) in reducing the fibrotic healing response of flap margins following femtosecond laser in situ keratomileusis (FS-LASIK). Methods: In this prospective, randomized, interventional, observer-masked trial, 41 patients (82 eyes) with myopia and/or myopic astigmatism were scheduled to undergo FS-LASIK. After surgery, patients were fitted with a BCL in one eye (BCL eyes, n=41) but not in the contralateral eye (control eyes, n=41), following randomized allocation of the BCL to the left or right eye of ea...

This study aimed to compare the changes in anterior corneal surface aberration after SMILE versus Q-FS-LASIK. This was a prospective, observational cohort study. Patients with myopia and myopic astigmatism underwent SMILE or Q-FS-LASIK at Hangzhou MSK Eye Hospital between January 2015 and November 2015. High order aberration (HOA), primary spherical aberration (PSA), primary coma aberration (PCA), primary vertical coma aberration (PVCA), and primary horizontal coma aberration (PHCA) were assessed using pre- and postoperative Sirius scanning. Both surgery were associated with significant increases in postoperative HOA, PS...
