Abstract EN
Purpose: To evaluate changes in visual outcome, refractive error and corneal asphericity after implantation of intracorneal ring segments (ICRS) (keraring) for the treatment of keratoconus Setting: Memorial institute for ophthalmic research, Egypt Methods: This study was conducted on 23 eyes of 17 patients with keratoconus.
ICRS was implanted intrastromally in the cornea as a treatment for keratoconus.
One or two rings with thicknesses ranging from 150 µm to 300 µm and arc lengths ranging from 160o to 210o were implanted.
Uncorrected visual acuity (UCVA),best corrected visual acuity (BCVA)and refractive error (sphere, cylinder)changes were assessed.
Keratometric values (k1,K2,Kmax)and corneal asphericity values anterior and posterior respectively(Q ant and Q post ) were obtained from Pentacam .
Results: There was clinically significant improvement regarding UCVA from 0.1±0.04 to 0.31±0.17 and improvement in BCVA was from 0.37±0.15 to 0.46±0.1.
The spherical and cylindrical errors significantly decreased postoperatively (p
