Abstract Details

Purpose:

To evaluate the efficacy and safety of Implantable collamer lenses (ICLs) in hyperopic astigmatism in a tertiary center at Eastern Province of Saudi Arabia.

Setting:

Dhahran Eye Specialist Hospital, Alkobar, Kingdom of Saudi Arabia.

Methods:

This retrospective cohort study, which took place between January 2017 and March 2018, included hyperopic patients operated for ICL implant who were assessed prior to and 12 months after surgery. Uncorrected and best corrected visual acuity (UCVA) (BCVA), refractive status, central corneal thickness, endothelial cell count (ECC), white to white corneal diameter (WTW), anterior chamber death (ACD) and intraocular pressure (IOP) were measured before and 12 months after intervention. Intraoperative and postoperative complications were noted. Success was defined as equal to preop BCVA or 2 lines improvement in the preimplantation BCVA 12 months after surgery.

Results:

We studied 26 eyes with hyperopic high astigmatism of 13 patients. The success of providing preoperative BCVA or more uncorrected visual acuity was successfully maintained in the majority of our cases (85%). The reduction of spherical and cylindrical refractive error 12 months after ICL implant was median 6.1 (IQR 4.75; 7.0) and -0.75 (IQR -1.5; 0.0) respectively. The ECC significantly reduced from median 2,870 to 2,672 per mm2 at 12 months (Wilcoxon (W) P=0.001). IOP significantly declined from 16 to 12mmHg at 6 and 12 months (Friedman p <0.001). The ACD demonstrated no significant variations (W P = 0.66).

Conclusions:

ICLs seem to be effective in providing spectacle-free functional vision in most of hyperopic eyes. it is associated with a good refractive predictability. However, their endothelial status should be monitored over a long period of time.
