Abstract Details

Purpose:

To determine the safety, efficacy and topographic changes of the New Asymmetric intracorneal ring segments with a progressive thickness on patients with duck like phenotype Keratoconus

Setting:

Muscat Eye Laser Center, Muscat, Sultanate of Oman.

Methods:

This prospective study included 12 eyes of patients with a mean age of 22 years with duck like phenotype Keratoconus who underwent Femtosecond assisted implantation of a New Asymmetric intracorneal ring segments with a progressive thickness kerarings AS5-160° (Mediphacos, Belo Horizonte, Brazil). Follow-up was performed at 1 day, 1 week and 1 month, with pre-operative and post-operative evaluation including; UDVA, CDVA, refraction, keratometry and Scheimpflug imaging (Sirius, CSO Inc.)

Results:

12 eyes were included, Mean preoperative sphere of -1,10D and cylinder of -3,20D, the mean postoperative sphere was -0,37D and cylinder -1,31D, mean preoperative Kmean 46.89D and Kmax 53.38D, the postoperative Kmean 44.99D and Kmax 49.40D. Significant improvement (p<0.05) on Sphere, Cylinder, Kmean and Kmax. The mean UDVA gained lines was 4,4 and the CDVA gained lines was 1,6. All the eyes gained lines of UDVA and no eyes lost lines of CDVA.

Conclusions:

Early results with the New Asymmetric intracorneal ring segments with a progressive thickness, showed to be safe and effective to provide significant corneal flattening and visual improvement on duck like phenotype Keratoconus.
