Abstract Details

Purpose:

To determine indications for crosslinking (CXL) after intracorneal ring segments (ICRS) implantation by comprehensive treatment of progressive keratectasias of different types.

Setting:

Fyodorov Eye Microsurgery Complex, Moscow, Russia

Methods:

We performed 280 surgeries in 262 patients with progressive keratectasias: II-III stage keratoconus, PMD, post-traumatic, post-PK, post-LASIK. As a first step we implanted ICRS in all patients according to standard nomograms using ICRS produced by Fyodorov Eye Microsurgery Scientific-Experimental Production Plant, Moscow, Russia. The decision concerning an expediency of CXL was made 6 months later on the basis of viso- and keratometry, OCT-pachimetry and keratotopography maps. We performed CXL according to standard protocol in 51 eye of 51 patients. RESULTS The gained results after ICRS implantation we describe as stable throughout follow-up (48 months) and average indices showed: UCVA 0,40,14; BCVA 0,60,15; spherical equivalent – 3,851,5 D; cylindrical equivalent –1,50,2 D; refractive power in the area of maximal ectasia 460,5 D; central corneal thickness 44011m. After CXL procedure the indices change was insignificant.

Conclusions:

ICRS implantation is an effective method of progressive keratectasias treatment. CXL procedure is expedient in cases of high residual ametropias that are needed to be corrected by PRK and/or PIOL as a functional step of comprehensive keratectasia treatment (even by proved keratectasia stabilisation).
