METHODS:This prospective clinical study included patients who underwent ICRS implantation for keratoconus over a period of 1 year. On the day of the surgery and at least 1 month after ICRS implantation, the following measurements were made: corrected and uncorrected distance visual acuity, corneal tomography indices with the Pentacam (Oculus Optikgeräte GmbH), biomechanically corrected intraocular pressure (bIOP), Corvis ST DCR parameters, integrated inverse concave radius (1/R), deformation amplitude ratio (DA ratio), stiffness parameter at first applanation (SP-A1), stress–strain index (SSI), and highest concavity radius (HRC). RESULTS:Fifty-one eyes of 40 patients were included with a median follow-up time of 3 months (interquartile ratio [IQR]: 2 to 6 months). Statistical analysis showed that ICRS implantation did not affect corneal biomechanical measurements evaluated with the Corvis ST, which was demonstrated by non-significant changes in the SP-A1 (P = .637), 1/R (P = .647), HRC (P = .177), DA ratio (P = .735), and SSI (P = .501). Additionally, the results showed that bIOP measurements were not significantly affected by ICRS implantation (P = .113). CONCLUSIONS:ICRS implantation does not affect corneal biomechanical measurements in early follow-up.engjournal articlehttps://doi.org/10.3928/1081597X-20220202-01https://journals.healio.com/doi/full/10.3928/1081597X-20220202-01restricted access617.7-089.243681.73617.713-007.64Intracorneal ring segmentkeratoconusICRSCorneal responseCorvis STÓptica y optometríaMateriales ópticos2209 Óptica2209.14 Propiedad ópticas de los sólidos
