. resuLts. Mean BCVA was improved from 0.0075 ± 0.08 logMAR to 0.025 ± 0.05 logMAR postoperatively. Average keratometry reduced from 44.9 ± 1.9 D to 39.8 ± 3.9 D. Mean minimal corneal thickness reduced from 504 ± 16.7 μm to 405 ± 41 μm. None of the cases developed regression, corneal ectasia, or corneal haze. ConCLusions. Photorefractive keratectomy combined with high-fluence corneal collagen crosslinking (PRK XTRA) appears to be a safe and effective treatment for patients who are not good candidates for LASIK.
This is a case report of a patient who developed dense subepithelial corneal infiltrates after epidemic keratoconjunctivitis and was treated with phototherapeutic keratectomy (PTK). The purpose of this case report is to explain the surgical technique and the results of PTK procedure.
This is a case report describing a planned routine cataract surgery that was complicated intraoperatively by breakage of the trailing haptic of the intraocular lens. The possibility of lens implantation despite the broken haptic is discussed, and the patient's postoperative course one month after the surgery is described, in this report.
This is a case report of two patients who underwent presbyopia correction with KAMRA corneal inlay (KAMRA; AcuFocus, Irvine, CA) combined with LASIK surgery. The surgical technique is thoroughly explained, as well as the advantages and disadvantages of the procedure. In both patients, near uncorrected visual acuity significantly improved and distance uncorrected visual acuity remained unchanged. There were no changes in the corneal topography after the corneal inlay implantation.
MateriaLs and Methods. Twenty eyes (20 patients) were treated with partial transepithelial topography-guided PRK combined with collagen crosslinking. Patients were evaluated preoperatively for best spectacle corrected visual acuity (BSCVA), clinical signs of keratoconus via slit lamp examination, and Scheimpflug-generated corneal topography. All eyes were treated with Amaris 750s Excimer Laser and KXL system. resuLts. Mean BCVA was improved from 20/100 to 20/25, postoperatively. Mean flat K was 46.8 ± 0.14 D preoperatively and was reduced to 45.2 ± 0.7 D postoperatively. Mean steep K was reduced from 50.2 ± 0.10 D to 47 ± 0.6 D. Total corneal astigmatism was 4.5 ± 0.14 D and decreased to 2.5 ± 0.10 D postoperatively. Average thinnest pachymetry was reduced from 465 ± 9.9 μm to 416 ± 11.3 μm. Total RMS (corneal aberrations) was 15.5 ± 7.4μm and was significantly reduced to 5.5 ± 2 μm. ConCLusions. Partial transepithelial topography-guided PRK combined with collagen crosslinking can benefit patients fitting the criteria for such a procedure, by stabilising their cornea as well as improving their BSCVA.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
