Clinical Outcomes of Modified Manual Deep Anterior Lamellar Keratoplasty for Eyes with Previous Radial Keratotomy.

: The aim of this study was to evaluate the intraoperative complications and visual outcomes of manual deep anterior lamellar keratoplasty (mDALK) in patients who underwent previous radial keratotomy (RK) for myopia. : The notes of patients who underwent mDALK after RK at three different hospitals-San Giovanni Addolorata Hospital (Rome, Italy), Mount Saint Joseph Hospital (Vancouver, Canada), and Tor Vergata University Hospital (Rome, Italy)-were retrospectively reviewed. We analyzed the manual dissection success rate and conversion to penetrating keratoplasty (PK), the residual recipient stromal thickness, the postoperative corrected distance visual acuity (CDVA), postoperative refraction, and topographic astigmatism.

Intraocular Lens Power Calculation in Eyes After Myopic Laser Refractive Surgery and Radial Keratotomy: Bayesian Network Meta-analysis.

Purpose: To compare the accuracy of formulas for calculating intraocular lens power in eyes after myopic laser refractive surgery or radial keratotomy.

Design: Bayesian network meta-analysis.

Methods: PubMed, Embase, the Cochrane Data Base of Systematic Reviews, and the Cochrane Central Register of Controlled Trials databases were searched for retrospective and prospective clinical studies published from January 1, 2012, to August 24, 2022.

Rare case of corneal keloid following radial keratotomy for myopia.

An adult male in his 50s presented with complaints of glare and gradual, painless, progressive diminution of vision in the right eye (RE). Visual acuity in RE was noted to be 2/60, and slit lamp biomicroscopy revealed a pearly grey-white elevated corneal opacity measuring 4 mm × 3 mm, obscuring the visual axis. There was no history of ocular trauma or infection.

Intraocular lens power calculation after radical keratotomy and photorefractive keratectomy: A case report.

Rationale: To report a rare case of calculating the IOL power in a cataract patient who underwent both radial keratotomy (RK) and photorefractive keratectomy (PRK).

Patient Concerns: A 48-year-old woman underwent bilateral RK at age 22 and bilateral PRK at age 46. She developed bilateral corneal haze and corneal endothelial inflammation and received steroids therapy for long time after PRK.

Cataract Surgery after Radial Keratotomy with Non-Diffractive Extended Depth of Focus Lens Implantation.

Radial keratotomy was a popular surgical procedure used to treat myopia. Patients who underwent radial keratotomy several years ago, are currently reporting to the ophthalmologist due to worsening of vision associated with age-related cataracts. In this case report we present a case of a 60-year-old woman who underwent radial keratotomy with 16 incisions in the right eye and 12 incisions in the left eye.

Clinical experience with adjustable scleral lenses.

Purpose: The aim of this study was to evaluate the fitting process of a scleral lens that allows several parameter adjustments during trials and after the initial period of use. In addition, we verified which adjustments were needed and used the most, their indications, and how often these resources were used, and checked the results.

Methods: Scleral contact lens fittings in a private clinic setting were prospectively analyzed in a sequential, non-randomized, and non-comparative manner.

[Radial keratotomy: history and current state].

Results of clinical use of the radial keratotomy (RK) surgery are presented in the format of a lecture and a summary. The analysis encompasses the mechanism of changes in corneal refraction, immediate intra- and postoperative complications, so-called secondary symptoms and long-term effects (addition of various pathological processes, influence of corneal changes on the results of diagnostic tests and treatment methods) of the surgery.

Biology of keratorefractive surgery- PRK, PTK, LASIK, SMILE, inlays and other refractive procedures.

The outcomes of refractive surgical procedures to improve uncorrected vision in patients-including photorefractive keratectomy (PRK), laser in-situ keratomileusis (LASIK), Small Incision Lenticule Extraction (SMILE) and corneal inlay procedures-is in large part determined by the corneal wound healing response after surgery. The wound healing response varies depending on the type of surgery, the level of intended correction of refractive error, the post-operative inflammatory response, generation of opacity producing myofibroblasts and likely poorly understood genetic factors. This article details what is known about these specific wound healing responses that include apoptosis of keratocytes and myofibroblasts, mitosis of corneal fibroblasts and myofibroblast precursors, the development of myofibroblasts from keratocyte-derived corneal fibroblasts and bone marrow-derived fibrocytes, deposition of disordered extracellular matrix by corneal fibroblasts and myofibroblasts, healing of the epithelial injury, and regeneration of the epithelial basement membrane.

Refractive surgery in the HIV-positive U.S. Military Natural History Study Cohort: complications and risk factors.

Purpose: This study sought to assess the frequency of refractive surgery complications in HIV+ individuals and related risk factors.

Settings: Multiple centers in the United States.

Design: Prospective observational cohort study.

Evaluation of total keratometry and its accuracy for intraocular lens power calculation in eyes after corneal refractive surgery.

Purpose: To compare the accuracy of total keratometry (TK) and standard keratometry (K) from a swept-source optical coherence tomography biometer for intraocular lens (IOL) power calculation in eyes with previous corneal refractive surgery.

Setting: Cullen Eye Institute, Baylor College of Medicine, Houston, Texas, USA.

Design: Retrospective case series.

Lensectomy after radial keratotomy: 1-year follow-up.

Purpose: To report visual and refractive results in radial keratotomy (RK) patients that underwent a cataract surgery with a monofocal intraocular lens (IOL) implantation with 1 year of follow-up.

Methods: Twenty-eight eyes of 15 patients with cataract and the previous RK were included. All eyes underwent phacoemulsification and monofocal IOL implantation.

Refractive correction with multifocal intraocular lenses after radial keratotomy.

Purpose: To assess visual and refractive results of multifocal intraocular lens (IOLs) implantation for refractive correction after radial keratotomy (RK).

Methods: In a retrospective non-comparative interventional case series, we analyzed the outcomes of multifocal IOL implantation performed in the context of cataract or refractive lens exchange surgery following RK. A total of 17 eyes from nine patients were included in the study.

Implantable Collamer Lens for Management of Pseudophakic Ametropia in Eyes With a Spectrum of Previous Corneal Surgery.

Methods: Forty-nine pseudophakic eyes of 40 patients in which myopic, hyperopic, or toric ICLs were implanted were retrospectively analyzed.
