Abstract
Purpose :
The selection of intraocular lens (IOL) among their different types in high myopic patients is until now a controversial topic among surgeons.
We performed a retrospective, single center, observational clinical study to report the tracking trends in monofocal, bifocal and trifocal IOLs use, and their visual outcomes in high myopic patients.
Methods :
We include all the patients who underwent cataract surgery between 2011 and 2021, with axial lengths (AxL) between 25.00 mm and 29.99 mm, disregarding another ocular pathology. Cohort groups were defined by IOL type (monofocal, bifocal, trifocal) and AxL. AxL measurements were obtained by optic biometry. The distribution of cases over time according to type of IOL and AxL was analyzed. Efficacy was calculated by comparing Preoperative best corrected visual acuity (BCVA) and postoperative uncorrected visual acuity (UCVA) in LogMAR units, and safety by comparing preoperative and postoperative BCVA. The statistical analysis was performed with IBM SPSS Statistics for Macintosh, Version 29.0 (Armonk, NY: IBM Corp).
Results :
A total of 6176 cases were included, 2544 (41.19%), 1385 (22.43%), 2247 (36.38%) with monofocal, bifocal and trifocal IOL, respectively. Regarding AxL, 2316 (37.50%), 1502 (24.32%), 1005 (16.27%), 783 (12.68%), 570 (9.23%) were between [25.00-25.99mm], [26.00-26.99mm], [27.00-27.99mm], [28.00.28.99mm] and [29.00-29.99mm], respectively.
Trifocal IOL use increased over the 10 years period from 1% of cases to 42%, with the highest value in 2016 (62%), meanwhile monofocal and bifocal IOL use decreased.
Efficacy (p=0.9945; ) and safety (p=0.8646) outcomes did not present a statically significant difference between each group.
Conclusions :
Rates of trifocal IOL implantation performed in high myopic patients have increased over time, showing no differences in terms of visual outcomes from those with monofocal and bifocal IOLs, regardless AxL.
