Abstract
Purpose: We evaluated the refractive visual outcomes and efficacy of Transepithelial Photorefractive Keratectomy (TransPRK) using Smart Pulse Technology with static and dynamic cyclotorsion and the AMARIS 1050 Hz RS laser platform from Schwind in the eyes after a refractive lens exchange. Setting/Venue: Aurelios Augenlaserzentrum, Recklinghausen. Methods: We retrospectively evaluated the data of 552 consecutive eyes treated with refractive lens exchange between 2016 and 2019. A total of 47 eyes (8.5%) required a touch up after the clear lens exchange. From 43 eyes of 43 patients, we obtained a minimum follow up of 3 months. In all cases, we performed a TransPRK with a minimum optical zone of 7.2 mm, centering the ablation on the vertex of the cornea. Results: The average age of the treated eyes was 57 years old, with a range between 48 and 68 years. The mean treated sphere was 0.42 diopters (D), with a range between −1.0 and +1.75 D. The mean astigmatism was 1.06 D. Postoperatively, after laser vision correction, we reduced the sphere to a mean of 0.11 D (range −0.5 to +0.75 D), and, postoperatively, the mean astigmatism was 0.25 D (range −0.75 to 0 D). The predictability for a spheric equivalent (SEQ) of 0.5 D was 91%, and for 1 D it was 100% of the cases. No eye lost more than one Snellen line. Conclusions: TransPRK with smart pulse was predictable for correcting ametropia after Clear Lens Surgery.
Highlights
Residual refractive errors are not tolerated in patients treated with refractive lens exchange and premium lenses; to maximize patient satisfaction and obtain a good postoperative uncorrected visual acuity (UCVA), we need to perform, in some cases, a second surgery
The aim of this study was to evaluate the efficacy of correcting the residual refractive error using transepithelial photorefractive keratectomy (TransPRK) after clear lens exchange (CLE)
The group of eyes that we analyzed was composed of eyes with preoperatively good visual acuity in which we performed a CLE, and the expectations of this group of patients is high
Summary
Residual refractive errors are not tolerated in patients treated with refractive lens exchange and premium lenses; to maximize patient satisfaction and obtain a good postoperative uncorrected visual acuity (UCVA), we need to perform, in some cases, a second surgery. There are similar studies analyzing the results of photorefractive keratectomy (PRK) [3,4,5,6] or laser in situ keratomileiusis (LASIK) [8] after cataract surgery. In our opinion, this is the first study analyzing eyes treated with clear lens exchange followed by the TransPRK method
