Abstract Details

Purpose:

To show efficacy of half fluence cross linking with intraocular implantable phakic collamer lens (IPCL, Care group inc.) implantation in cases of post lasik regression.

Setting:

Ruby Eye Hospital, Berhampur, Odisha, India

Methods:

10 eyes of 5 patients were analysed for post lasik refractive error. All patients were investigated with pentacam to look for signs of ectasia. All had progressive increase in refractive error but none had topographic signs of classic ectasia. Eligible patients underwent half fluence cross linking. After 3 months they were scheduled for intraocular phakic IOL implantation. Eyes were targeted for emmetropia. Mean pre operative uncorrected visual acuity was 1.4 decimals in logmars. Mean pre operative refractive error corrected 12.65D (Min: 6 and Max : 22). Mean preoperative simulated keratometry 36.3 D ( Min: 34D and max: 38.5).

Results:

Mean post operative spherical equivalent recorded was 0.75D (Min: 0.25 and Max: 1.37). Mean Post op unaided visual acuity recorded 0.13 logmar units +/-0.12 ( Min 0 and Max 0.3). Patients had mean follow up of 1.54 years +/-0.33 and vision was stable during this period. Post operative keratometry remained stable during the follow up period. Contrast sensitivity at 6 months improved significantly with p value <0.0001. Corneal thickness showed no signs of alteration.

Conclusions:

Half fluence collagen cross linking in combination with sequential implantation of phakic iol in cases of post lasik regression can be considered as an effective and stable procedure providing successful outcome.
