Abstract Details


To evaluate clinical results of intrastromal corneal ring segments (ICRS) in a large series of post-laser in situ keratomileusis (LASIK) ectasia and determine which clinical parameters were related to the success of this technique.


Vissum, Alicante, Spain.


Intrastromal corneal ring segments were implanted to correct the spherocylindrical error and improve visual acuity. Based on a previously described grading system, the best indications for ICRS implantation to treat post-LASIK ectasia were evaluated. The variables related to favorable outcomes over a 12-month follow-up were determined.


Patients who lost 2 or more lines due to post-LASIK ectasia had a mean gain of 2.89 lines of corrected distance visual acuity (CDVA) after ICRS implantation (P<.001) and a mean CDVA of 0.81 . In contrast, patients who did not lose vision after ectasia had a mean loss of 2.00 lines of CDVA after the ICRS implantation (P<.001).


The best indications for ICRS are those patients that lose more lines due to the ectatic process. Patients who do not have vision loss after ectasia and those classified as grade 1 should not be considered candidates for ICRS implantation.
