Abstract Details

Purpose:

To evaluate of myoring implantation effect on corneal asphericity in moderate and severe keratoconus

Setting:

Eye Research Center, Farabi Eye Hospital, Tehran University of Medical Sciences, Tehran, Iran.

Methods:

This cross- sectional study comprised 32 keratoconic eyes of 28 patients with a mean age of 26/75. Preoperative and postoperative uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), manifest refraction, corneal asphericity at 6,7,8,9 and 10 mm optical zone in superior, inferior, nasal, temporal and central areas, thinnest location value and keratometry readings were the main outcome measurse of the study.

Results:

A significant improvement in UDVA and CDVA was observed 6 months after surgery (P< 0.001), which was consistent with the significant reduction in sphere (4/67D) and cylinder (2/19D). in addition, a significant reduction in the main corneal asphericity at 6,7,8,9 and 10 mm optical zone in superior, inferior, nasal, temporal and central areas was found (p<0/001). The mean thinnest location value decreased from 437/15 �Â�± 30/69 to 422/81 �Â�± 36/91. Furthermore, a significant corneal flattening was found, the k1, k2, and km changes was 5/32 D, 7 D, 6/17 D Respectively (p<0/001).

Conclusions:

MyoRing implantation in keratoconus allows successful corneal modeling and provides significant improvement in visual acuity and refractive error.
