Purpose

In recent times there has been increasing interest and expectations with premium (advanced technology) intraocular lenses (IOLs). Refractive surprises can occur unexpectedly following lens surgery using monofocal, toric and multifocal IOLs. Here we examine the role of therapeutic transepithelial photorefractive keratectomy (t-PRK) for correcting post cataract refractive error and discuss principles of case selection, challenging case examples and decisions on when cataract or laser surgery should come first

Setting

Laser vision clinic in Vancouver

Methods

Retrospective case series of patients undergoing therapeutic PRK to treat refractive surprises after lens surgery using monofocal, toric and multifocal IOLs

Results

16 patients who underwent therapeutic PRK for correcting post cataract refractive error. Mean spherical equivalent reduced from 0.88±1.62D to 0.24±1.20D. 75% (12/16) achieved 20/40 UDVA or better. 50% (8/16) achieved 20/25 or better.

Conclusions

With increased demand and higher expectations minor post-opertiave refractive errors can be poorly tolerated by patients with premium IOL implantation. Compared to an intraocular procedure therapeutic PRK surgery is a safer, less invasive and more accurate way to treat refractive error following lens surgery.
