Purpose:
To assess clinical outcomes following implantation of the Tecnis Toric intraocular lens (IOL; Abbott Medical Optics) to correct pre-existing corneal astigmatism in patients undergoing routine cataract surgery.
Setting:
Four hospital eye clinics throughout Europe.
Methods:
This prospective observational study included 67 eyes of 60 patients with at least 0.75 D of pre-existing corneal astigmatism undergoing routine cataract surgery. Phacoemulsification was performed, followed by insertion and alignment of the Tecnis Toric IOL. Patients were examined 4 to 8 weeks post-operatively; uncorrected distance visual acuity (UDVA), best-corrected distance visual acuity (CDVA), manifest refraction and keratometry were measured. Individual patient satisfaction regarding uncorrected vision and the surgeon’s assessment of ease of handling and performance of the IOL were also documented. In a subset of eyes, the cylinder axis of the toric IOL was determined by dilated slitlamp examination. RESULTS 4-8 weeks post-operatively, mean UDVA was 0.15 ± 0.17 logMAR, and 20/40 or better in 88% of eyes. The mean refractive cylinder decreased significantly following surgery, from -1.91 ± 1.07 to -0.67 ± 0.54 DC; no significant change in keratometric cylinder was observed. Mean IOL rotation was 3.36 ± 3.30 degrees (range 0-12 degrees). The good standard of UDVA achieved resulted in high levels of patient satisfaction.
Conclusions:
Implantation of the Tecnis Toric IOL is an effective, safe and predictable method to manage corneal astigmatism in patients undergoing routine cataract surgery.
