Correction of high astigmatism in cataract patients with a toric IOL with a Z-haptic


A retrospective study of cataract patients who underwent phacoemulsification with implantation of the Toric Microsil 6116 TU IOL is described.

Nowadays, eliminating visually significant preexisting astigmatism at the time of cataract surgery has become a key factor for a successful outcome. The advent of toric intraocular lenses (IOLs) has been a major breakthrough in refractive correction because it offers the possibility of correcting pre-existing corneal astigmatism and spherical refractive errors during cataract surgery with only slight adjustments in technique. It has been estimated that approximately 22% of cataract patients have corneal astigmatism of 1.5 D or higher and would benefit from toric IOL implantation.1 Many manufacturers now supply toric IOLs.2 However, options for treating patients with very high spherocylindrical errors are still limited.

Our study

Patients were observed 1 day, 1 week, 1, 3 and ≥6 months (range 6 to 18 months) after surgery. Monocular distance uncorrected visual acuity (UCVA), refraction, keratometry and IOL alignment were recorded at each follow-up visit.
