“…Photorefractive keratectomy (PRK) is a safe and effective procedure to correct residual refractive errors following cataract surgery with premium IOL [ 5 , 19 ]. We decided to perform a transepithelial approach in our group of eyes.…”

“…We can change the implanted intraocular lens or add a second intraocular lens (piggyback method) [ 1 , 2 ]; these are options if the ametropia is very large; a third alternative is to use refractive corneal surgery. Laser vision correction (LVC) has been shown to be predictable and effective for correcting small amounts of spherical and cylindrical errors after intraocular lens surgery [ 3 , 4 , 5 , 6 ].…”

“…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). 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.…”

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.

“…[ 1 ] Residual astigmatism after cataract surgery has been shown to affect the quality of life and reduce patient satisfaction, necessitating its correction with spectacles, limbal relaxing incisions (LRIs) or laser ablative surgery. [ 2 3 4 5 6 ] These approaches suffer from limitations such as lack of precision, chances of regression, variable healing responses, under-correction/over-correction, loss of best spectacle-corrected visual acuity, risk of infection, and post-operative dry eye. [ 2 3 4 5 6 7 ] Also, some patients do not prefer wearing spectacles after cataract surgery.…”

[ 2 3 4 5 6 7 ] Also, some patients do not prefer wearing spectacles after cataract surgery. The ability of toric IOLs to treat pre-existing corneal astigmatism along with surgical aphakia, particularly in cases of significant corneal astigmatism was shown to provide a substantial advantage over LRIs, or excimer laser surgery.…”

Purpose: To evaluate the clinical performance and rotational stability after implantation of Eyecryl Toric monofocal IOL following cataract surgery. Methods: Patients undergoing phacoemulsification for age-related cataract and satisfying the eligibility criteria were implanted with Eyecryl Toric IOL. All implantations were done under balanced salt solution. A marker-less system Callisto Eye (Carl Zeiss Meditec, Germany) was used to guide the intra-operative alignment of the toric IOL. Results: A total of 50 eyes from 39 patients with mean age of 68.2 ± 8.7 years were included in the study. At 12 months, 82% (41) eyes had cumulative UDVA of 20/20 or better. Post-op SE refraction accuracy was within ± 0.50 D for 94% ( n = 47) eyes and refractive cylinder accuracy was within ≤0.50 D in 98% ( n = 49) eyes. Average post-op rotation at 1 year was 4.06 ± 2.15 degrees. Eighty-four percent of eyes were within 5 degrees and 16% were within 6-10 degrees of intended axis. Two eyes required IOL re-positioning due to significant rotation of the toric IOL (>10 degrees), identified within the 1 st week after surgery. Conclusion: Eyecryl toric IOL demonstrated the ability to achieve a significant reduction in astigmatism, improved UDVA outcomes, high levels of spectacle independence, low rates of intra-operative injector related complications and good rotational stability at 12 months post-op.

Purpose To compare the visual outcomes, predictability and rotational stability following implantation of Eyecryl toric versus TECNIS toric intraocular lenses. Methods This retrospective study included 100 eyes of 78 eligible patients who underwent phacoemulsification followed by implantation of either Eyecryl Toric IOL or TECNIS Toric IOL (n = 50 eyes in each group), using an intraoperative image-guided marker less system. All toric IOL implantations were performed under balanced salt solution. At 2 weeks, 3 months and 6 months, uncorrected (UDVA) and corrected distance visual acuity (CDVA), spherical equivalent refraction, residual astigmatism, and rotational stability of the toric IOL was evaluated and compared. Rotational stability was assessed using ray tracing.Results Mean age of the participants was 67.8 ± 9.26 years in Eyecryl toric group and 64 ± 11 years in TECNIS toric group. The mean pre-op corneal astigmatism was 1.75 ± 0.62 D and 2.00 ± 0.71 D in the Eyecryl and TECNIS group, respectively (p = 0.07). At 2 weeks and at 6 months post-op, there was no statistically significant difference between the UDVA, CDVA, and residual astigmatism between the two groups (p \ 0.05). Mean post-operative toric IOL rotation was 3.94 ± 2.27 degrees in the Eyecryl Toric group, and 4.44 ± 2.77 degrees, in the TECNIS Toric group, respectively, the difference was not statistically significant (p = 0.32). One IOL in the Eyecryl group and two IOLs in the TECNIS group required re-positioning for significant post-op rotation at 1 week post-op. Conclusion At 6 months, both Eyecryl toric and TECNIS toric IOLs showed comparable post-operative outcomes in terms of UDVA, CDVA, residual astigmatism and rotational stability.
