The authors report in a retrospective study, the results of myopic keratomileusis. 40 eyes were operated on at the department of ophthalmology of Hotel-Dieu Hospital in Paris, with a range follow-up of 6 to 24 months. The mean pre-operative spherical equivalent was - 15.08 +/- 3.32 D., and the mean post-operative spherical equivalent was - 5.02 +/- 3.75 D. relative to preoperative conditions, best corrected visual acuity were unchanged in 6 cases, improved in 16 cases and diminished in 18 cases. The predictability of results was better for patients with myopia in the range of - 9 to - 16 D. During the first post-operative year, a mean regressive tendency of 3 diopters was noted. Complications are reported and analysed. Myopic keratomileusis is indicated for myopia between - 10 and - 16 D., when correction by contact lenses has failed. Candidates for surgery must be informed and consent about possibilities, limits and risks of the procedure.

Background/aims: To identify the risk factors for neuropathic corneal pain (NCP) following corneal refractive surgery and to report its clinical manifestations, imaging and proteomic characteristics.
Methods: This 1 year prospective cohort study included 100 eyes that underwent small incision lenticule extraction (SMILE) or laser-assisted in situ keratomileusis (LASIK). Ocular surface assessments, in-vivo confocal microscopy scans, tear neuromediators and proteomics analyses were performed.

Introduction: This study aimed to compare changes in retinal oxygen saturation 1 month after femtosecond-assisted laser in situ keratomileusis (FS-LASIK) in Chinese adults with myopia using retinal oximetry.
Methods: In this prospective, observational, single-center cohort study, Chinese adults aged 18-45 years with myopia were categorized into four groups according to spherical equivalent (SE), with 66 eyes characterized as low myopia (LM -3.00D < SE ≤ -0.

The purpose of this study was to evaluate the stability of small-incision lenticule extraction (SMILE) and laser in situ keratomileusis (LASIK) when ascending from near sea level to an altitude of 3874 m. The visual acuity (VA), intraocular pressure (IOP), spherical equivalent refraction (SER) and biometric parameters of 20 normal subjects (40 eyes, controls) and 36 subjects who underwent corneal refractive surgery (35 eyes with SMILE and 36 eyes with LASIK) were examined in Chongqing (C, 500 m above sea level) and 7-10 days after a collective travel to Shigatse (S, 3874 m above sea level). SER and corneal thickness (CT) were choosed as main indicators of the stability of corneal refractive surgery at high altitude.
View Article and Find Full Text PDFPurpose: To evaluate residual refractive errors after intraocular lens (IOL) extraction and the safety and effectiveness of refractive correction procedures.
Methods: The eligibility criteria for this systematic review were patients who had undergone cataract or clear lens extraction and had experienced residual refractive error. All study designs were considered for inclusion and non-English publications, non-peer reviewed articles, books, and systematic reviews were excluded.
Refractive Prediction Accuracy Using Intraoperative Aberrometry versus Barrett True-K Formula Following Corneal Refractive Surgery.

Alcon Vision LLC, Fort Worth, TX, USA.
Purpose: To compare the refractive prediction accuracy of the Optiwave Refractive Analysis (ORA) SYSTEM with the Barrett True-K (BTK) formula in calculating intraocular lens (IOL) power in eyes that underwent cataract surgery after previous myopic photorefractive keratectomy (PRK) or laser-assisted in situ keratomileusis (LASIK).
Methods: This retrospective study evaluated patients aged ≥22 years with prior myopic PRK or LASIK who underwent unilateral or bilateral cataract removal and monofocal IOL implantation using the ORA SYSTEM at 177 sites in the United States. Two datasets were analyzed: All Eyes (ie, all eligible eyes) and First Surgery Eyes (ie, each patient's first implanted eye).
