Abstract Details

Purpose:

To evaluate the efficacy and safety of MyoRing implantation into a corneal stromal pocket via Corneal intrastromal implantation system (CISIS) for keratoconus (KC) treatment.

Setting:

Egyptian Eye Academy and Benha University Hospital, Egypt.

Methods:

Non-randomized prospective clinical trial included 22 eyes of 22 KC patients. The MyoRing was inserted into a 300um corneal pocket centered on the corneal reflex. Follow up for 6 months with measurement of uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), and Pentacam corneal imaging was performed. Any surgical complication was reported.

Results:

There was high statistically significant improvement of UCVA, BCVA, K1, K2, and Km when comparing the preoperative with all postoperative values (p value <0.001). The mean UCVA increased from 0.12±0.17 to 0.5±0.24 and the mean BCVA from 0.3±0.143 to 0.7± 0.22 at 6 postoperative months (P<.001). The mean K1, K2 and Km decreased from 48.45±3.79, 54.46±3.94 and 51.31±3.56 to 45.79± 2.97, 42.56± 3.17and 49.07±3.33 at 6 postoperative months, respectively. Three cases of severe KC underwent position adjustment of the implant. No detectable intra- or postoperative complications were observed in any of the cases.

Conclusions:

MyoRing intrastromal implantation could represent an efficient, safe, modifiable and simple therapeutic option for KC management.
