| Abstract | ||||
| In this report we are presenting a 28-year-old female with right keratoconus grade3 and left keratoconus grade 2 with low degree refraction (spherical equivalent in right eye = -2.25 and +0.75D in left eye). Axial length measurement revealed short axial length (RE=19.63mm, LE=19.97 mm). After counseling the patient, the decision was to go for right simultaneous femtosecond intracorneal ring segments implantation with corneal collagen cross linking. UCVA, BCVA, sphere, cylinder, spherical equivalent, RMS total high order aberrations(HOA), RMS coma, and RMS astigmatism were measured pre- and postoperatively in the first week, 1 month, 3 month, 6 month. The results were favorable as regards improvement in UCVA, BCVA, with mild hyperopic shift in the sphere as expected with decrease in the cylinder, and induced flattening. As for HOA, coma and astigmatism; there was marked decrease. | ||||
