Creation of a Corneal Flap for Laser In Situ Keratomileusis Using a Three-Dimensional Femtosecond Laser Cut: Clinical and Optical Coherence Tomography Features

Optics
Laser in situ keratomileusis (LASIK) is the most frequently used technique for the surgical correction of refractive errors on the cornea. It entails the creation of a superficial hinged corneal flap using a femtosecond laser, ablation of the underlying ...

Rescue of Primary Incomplete Microkeratome Flap with Secondary Femtosecond Laser Flap in LASIK

Case Reports in Ophthalmological Medicine, 2014
For laser-assisted in situ keratomileusis (LASIK) retreatments with a previous unsuccessful mechanical microkeratome-assisted surgery, some surgical protocols have been described as feasible, such as relifting of the flap or the creation of a new flap ...

Corneal epithelial ingrowth after small incision lenticule extraction surgery: Insights from a case series and mechanistic studies

MedComm – Future Medicine, Volume 3, Issue 3, September 2024.
This study identifies mechanisms of epithelial growth post‐Small Incision Lenticule Extraction surgery and suggests preventive and treatment measures, including subflap debris removal, to address corneal epithelial ingrowth. Abstract Corneal epithelial ingrowth (EI) is a rare but significant complication following Small Incision Lenticule Extraction ...

Nonthermal phase transitions in semiconductors induced by a femtosecond extreme ultraviolet laser pulse [PDF]

, 2013
Part of Focus on High Energy Density Physics. In this paper, we present a novel theoretical approach, which allows the study of nonequilibrium dynamics of both electrons and atoms/ions within free-electron laser excited semiconductors at femtosecond time

Corneal Epithelial Thickness Mapping: A Major Review

Journal of Ophthalmology, Volume 2024, Issue 1, 2024.
The corneal epithelium (CE) is the outermost layer of the cornea with constant turnover, relative stability, remarkable plasticity, and compensatory properties to mask alterations in the underlying stroma. The advent of quantitative imaging modalities capable of producing epithelial thickness mapping (ETM) has made it possible to characterize better ...

Long‐Term Visual Quality and Pupil Changes after Small‐Incision Lenticule Extraction for Eyes without Preoperative Cylinder Refraction

Journal of Ophthalmology, Volume 2024, Issue 1, 2024.
Purpose. To investigate the long‐term changes in visual quality and pupil size after small incision lenticule extraction (SMILE) for eyes without preoperative cylinder refraction. Methods. Thirty‐three myopic eyes (33 patients) without preoperative cylinder refraction were corrected using SMILE.

Evaluation of interface quality in organ-cultured lamellar corneal transplants [PDF]

, 2012
Background: With increasing numbers of lamellar keratoplasties, eye banks are challenged to deliver precut lamellar donor tissue. In Europe, the most common technique of corneal storage is organ culture which requires a deswelling process before surgical
