Clinical Outcomes Using a Trifocal Intraocular Lens in Eyes After Previous Laser Corneal Refractive Surgery or Radial Keratotomy: 1-Year of Follow-Up.
Clin Ophthalmol
August 2025
Brussels Eye Doctors, Brussels, Belgium.
Purpose: To show the clinical outcomes after implantation of a diffractive trifocal intraocular lens (IOL) in eyes with previous laser-corneal-refractive-surgery (LCRS) or radial keratotomy (RK).
Methods: Eyes with previous LCRS (LASIK/PRK group) or RK (RK group) implanted with a diffractive trifocal IOL were enrolled in this retrospective study. Refraction and monocular Snellen decimal uncorrected-distance visual acuity (UDVA), corrected-distance visual acuity (CDVA), and uncorrected-near visual acuity (UNVA) were analyzed at 1-year.
The accuracy of VRF intraocular lens power calculation formula in cataract patients after radial keratotomy.
Int Ophthalmol
July 2025
Beijing Ophthalmology & Visual Sciences Key Laboratory, Beijing Tongren Eye Center, Beijing Tongren Hospital, Capital Medical University, Beijing, 100730, China.
Purpose: To investigate the accuracy of the VRF intraocular lens (IOL) power calculation formula in cataract patients after radial keratotomy (RK).
Methods: This was a retrospective study that reviewed and retrieved the medical history of patients after RK who underwent cataract surgery from April 1, 2021, to December 31, 2024, at Beijing Tongren Hospital. A total of 50 eyes of 27 patients were included.
Predicted Visual Impact of a Small Aperture Intraocular Lens in Reducing Higher Order Aberrations in Post-Radial Keratotomy Patients.
Vision (Basel)
May 2025
Department of Ophthalmology, Icahn School of Medicine at Mount Sinai, New York, NY 10029, USA.
The purpose of this study is to evaluate the potential impact of small aperture optics on corneal aberrations in post-RK patients. Preoperative data was evaluated from 32 eyes of 23 post-RK patients. Scheimpflug tomography was used to obtain measurements of corneal HOAs at 6-mm, 4-mm, and 2-mm corneal plane aperture diameters.

J Refract Surg
June 2025
Purpose: To review current guidelines for the prophylactic and therapeutic use of topical losartan to prevent and treat corneal scarring fibrosis in refractive surgery.
Methods: PubMed was used to search the medical literature.
Results: Scarring fibrosis of the cornea is typically associated with injury to, and defective regeneration of, the adjacent overlying epithelial basement membrane that controls transforming growth factor (TGF)-β passage into the stroma, leading to the development and persistence of myofibroblasts.
Asymmetric Presentation of Corneal Ectasia With Acute Hydrops 34 Years Following Bilateral Radial Keratotomy.
Cureus
April 2025
Department of Ophthalmology, Kyoto Prefectural University of Medicine, Kyoto, JPN.
Despite the subsequent emergence of more advanced refractive surgical techniques, ophthalmologists continue to encounter patients who have experienced long-term complications from radial keratotomy (RK). A notable complication of RK is corneal ectasia, which, although rare, can lead to significant vision impairment years after the procedure. The present case report details a 54-year-old male patient who developed unilateral corneal ectasia with acute hydrops 34 years following bilateral RK.
