Outcomes In The Correction Of Presbyopia And Astigmatism With A Presbyopic Transitional Conic Toric Iol

PURPOSE: To evaluate the effectiveness, stabilityand patient satisfaction after cataract or clear lens exchange surgery with implantation of Precizon Presbyopic Toric (Ophtec, Groningen, NED), a presbyopia correcting IOL with a transitional conic toric design.

Prospective, longitudinal and non-comparative clinical study in one single center.

This prospective, longitudinal, single-arm, non-interventional and non-comparative clinicalstudy involves 40 eyes of 20 patients. The main outcome parameters are postoperative corrected / uncorrected VA at distance, intermediate and near (LogMAR). Manifest refraction and IOL rotation are assessed as secondary outcome measures. Patient satisfaction and quality of vision will be evaluated through a questionnaire. Follow-up assessments areconducted six months post-surgery.

Preliminary results (16 eyes) show that at 6 months post-surgery, 95% and 100% of the eyes presented a spherical equivalent (SE) within ± 0.50D and ± 1.00D, respectively. The mean SE and refractive cylinder were 0.13 ± 0.28D and - 0.36 ± 0.22D, respectively. 95% of the eyes showed an uncorrected and corrected distance visual acuity (UDVA and CDVA) of 0.1LogMAR or better. The postoperative mean values of monocular UDVA and CDVA were -0.02 ± 0.09 and -0.06 ± 0.07 LogMAR, respectively. Monocular distance corrected intermediate visual acuity and distance corrected near visual acuities (DCIVA and DCNVA)demonstrated satisfactory outcomes, with mean values of 0.17 ± 0.07 and 0.22 ± 0.09 LogMAR, respectively.

The present study suggests that the use of the Precizon Presbyopic Toric IOL in cataract or refractive lens exchange patients with astigmatism, provides good visual acuity at all distances, accurate refractive outcomes, excellent rotational stability and high levels of patient satisfaction. Analysis of questionnaire data revealed that 70% of patients never or only occasionally experienced photic phenomena. Moreover, 95% of patients reported to be very satisfied with the overall outcome of the procedure. No patient required IOL realignment during the postoperative follow-up.
Given that this is an interim analysis, updated results will be presented at a more advanced stage of the study.
