"Comparison Of The Visual Outcomes And Rotational Stability Of Two Distinct Designs Of Monofocal Toric Iols Using The Hydroimplantation Technique."

The purpose of this study was to compare the visual outcomes and rotational stability between two different designs of Monofocal Toric IOLs using the hydro implantation technique.

The Prospective non-randomised comparative study was conducted by a Single Surgeon at Aastha Hospital, Anand, Gujarat, India between October 22 to May 24.

We conducted the study at a single centre in India in 115 eyes with preoperative cylinder of more than 1 D who underwent cataract surgery with the implantation of the Eyecryl Toric (ET) or AT Torbi 709M (AT) between October 22 to May 24. We assessed 1 day, 1 week and one-month post-operative visual outcomes, residual astigmatism (RA), and rotational stability (RS) of IOL.  All patients sought freedom from spectacles for distance vision and, advantages and disadvantages of both the IOLs were informed.

Analysis was conducted on 115 eyes from 82 patients (46 male and 36 female), with 65 eyes (44 patients) received Eyecryl Toric (ET) and 50 eyes (38 patients) received AT Torbi 709M (AT). At 1 months, the visual acuity of ET and AT were UCVA 0.16± 0.20 and 0.17 ± 0.17 logmar; p= 0.46 respectively. ET and AT showed postoperative RA of 0.02 ± 0.12 and 0.04 ± 0.53 D; p= 0.31 respectively. In both groups, the post-op RA was within ± 1.0 D in all eyes. On 1st day and 3 months post-op, IOL rotation in ET and AT were 3.94 ± 5.95 and 7.96 ± 23.93; p=0.13, 2.94 ± 2.62 and 3.40 ± 4.08; p=0.24, respectively.

The Eyecryl Toric and AT Torbi 709M intraocular lenses (IOLs) exhibited better visual acuity and decreased residual astigmatism post-cataract surgery. While the clinical significance was minimal, the Eyecryl Toric demonstrated superior rotational stability compared to the AT Torbi 709M IOL.
