Abstract Details


The main purpose of this study is to show that ICRS can be one solution to correct low myopia with keratectasia risk factors.


Service d'Ophtalmologie, Hôpital Morvan, Brest, France.


This retrospective case series comprised all patients who had ICRS Intacs® implantation to correct myopia in Brest from 2012 to 2015. For each patient an evaluation with visual acuity and manifest refraction was performed preoperatively. Ocular response analyzer (ORA) measure, Scheimpflug topography and Placido-based corneal topography were collected. Postoperatively the visual acuity uncorrected and corrected at 1 month, 3 months, 6 months and 1 year was collected. With these data the risk of ectasia was evaluated with Randleman Ectasia Risk Score System. Intacs® rings with a thickness of 0.20 to 0.45 µ were implanted in femtosecond laser-assisted intrastromal tunnels.


19 patients and 34 eyes were enrolled in this study.The mean age was 33 years old . 34 procedures were performed between 2012 and 2015. 23(70%) eyes had a low- myopia ( >-3D) and 10 (30%) a medium mypopia ( from -3D to -6D). 29(87%) eyes had an astigmatism lower than 1D. 30 (88%) eyes had a pachymetry lower than 510µ, 8 (23%) had a suspicious topography or a frustre keratoconus and 9( 26%) eyes had a pathological ORA. The mean uncorrected visual acuity after 1 year is 0.045 -LogMAR.


The ICRS is one of the solutions to correct low myopia with corneal risk factors for keratectasia. Additional procedure can be performed for the optimisation of the uncorrected visual acuity like PRK, but sparing corneal depth.
