Efficacy of Monofocal Toric IOL Implantation in Cataract Surgery
Narrative Responses:
Purpose
To evaluate the efficacy of the of AT-Torbi 709M Toric Intraocular Lens in correcting preoperative astigmatism in cataract patiens.
Methods
This prospective observational study included 33 eyes from 22 consecutive patiens (mean age 69.5 years) who had more than -1.00 diopter of keratometric astigmatism who underwent implantation of an AT-Torbi 709M Toric IOL with micro-coaxial cataract surgery. Patiens with ocular pathology or surgical complicatios were excluded. Outcomes of visual acuity, refractive and keratometric astigmatism after 1 and 3 months, follow-up were evaluated.
Results
At one month follow-up 69.70% of eyes showed an uncorrected visual acuity of 20/30 or better. The postoperative keratometric value was not different from the preoperative value and the mean reafractive astigmatism was reduced in 69.18% to -0.57 D from -1.86D (P=<0.0001). We compared the expected refraction from the Z-Calc On-Line IOL calculator with the refraction at 1month follow-up.
Conclusion
At 1 month follow-up showed that implantation of the AT-Torbi 709M Toric Intraocular Lens is an effective, safe and predictable method for managing corneal astigmatism in cataract patiens. The expected refractive result by the Z-Calc On-line IOL calculator was more accurate for spherical than cylinder error.
