Presbyopia Correction With Multifocal Toric IOL Implantation
Narrative Responses:
Purpose
The aim of the study was the possibility assessment of the presbyopia correction, changes in the activities of everyday life and satisfaction with vision in patients with previous corneal astigmatism after bilateral cataract surgery followed by posterior chamber implantation of multifocal toric intraocular lenses M-FLEX T (Rayner, UK)
Methods
The patients with corneal astigmatism higher than 1.5D motivated to reduced their dependency on glasses were qualified for presbyopia correction with multifocal toric intraocular lens implantation. The analyzed material consisted of 30 eyes in 15 patients, mean age 57.6, implanted with multifocal toric IOL M-FLEX T (Rayner, UK), the addition for near vision was +4,0D. The follow up time was 12-28 months. Functional results and clinical state during entire postoperative period was evaluated. We compared: pre- and postoperative UCDVA, BCDVA, UCNVA, changes of the postoperative objective refraction, contrast sensitivity, changes in the activities of everyday life and patients subjective satisfaction
Results
No statistically significant difference in pre- and postoperative corneal astigmatism was reported. Before surgery the mean UCDVA was 0,33±0,11, the mean BCDVA was 0,61 ±0,091. Post-op mean UCDVA was 0.99, UCNVA was J2 in 85% of eyes. The intermediate vision was satisfied in 91% of eyes. The mean contrast sensitivity improved postoperatively in all spatial frequencies (from 1.20, 1.28, 0.83, 038 pre-op to 1.48, 1.70,1.04, 0.40 post-op respectively). There is no coincidence between changes of the distance visual acuity and measures of the quality of life with the VF-14 index
Conclusion
The greatest advantage of the multifocal toric M-FLEX T IOL implantation is that it can provide good uncorrected distance and near visual acuities reducing the dependence on spectacles. Procedure is reasonable refractive surgery option for middle-aged patients
