“…In this study, both groups of patients achieved signi cant and stable improvement in UCVA and BCVA postoperatively, similar to previous research results [30,[33][34][35][36]. Meanwhile, the CDVA and UDVA of the LRI group were better than those of the TICL group at 1 month and 3 months postoperatively, which may be related to the accurate correction of AST.…”

Background To compare the safety, efficacy, predictability and stability of implantable collamer lens (ICL) implantation with limbal relaxing incision (LRI) and toric ICL (TICL) implantation for correcting corneal astigmatism in high myopic patients. Methods This prospective clinical study recruited high myopic patients with a preoperative cylinder ranging from − 1.5 D to -1.0 D. Patients were randomly divided into two groups: 35 eyes of 25 patients underwent independent TICL implantation (TICL group), and 35 eyes of 20 patients underwent ICL implantation combined with LRI (LRI group). Uncorrected distance visual acuity (UDVA) and corrected distance visual acuity (CDVA) were observed before and at the end of the 1st and 3rd months postoperatively. The outcomes considered were refraction and corneal topography preoperatively and 3 months postoperatively. The variation in astigmatism was analyzed using vector analysis, which included surgically induced astigmatism (SIA), target-induced astigmatism (TIA), and the correction index (CI). Safety, efficacy, predictability and stability were also analyzed. Results LogMAR UDVA and logMAR CDVA were significantly improved 1 and 3 months postoperatively in both groups (P < 0.001). LogMAR CDVA in the LRI group was significantly higher than that in the TICL group at 1 month postoperatively (P = 0.001); logMAR UDVA was significantly higher than that in the TICL group at 3 months postoperatively (P = 0.025). AST in the LRI group was significantly reduced postoperatively (P = 0.001); there was no significant difference in the TICL group (P > 0.05). There was no statistically significant change in SIA or TIA between the two groups (P > 0.05) 3 months postoperatively. The CI of the two groups indicated mild overcorrection, without a statistically significant difference between the groups (P > 0.05). No complications occurred during the 3-month follow-up. The short-term safety of the LRI group was significantly higher than that of the TICL group (1.18 ± 0.23 vs. 1.01 ± 0.39, P = 0.029). Conclusions LRI combined with ICL implantation is effective for correcting low to moderate astigmatism in the short term. The safety, correction effect of astigmatism and visual acuity are better than that of TICL implantation. LRI is feasible as an astigmatism correction method for patients with high myopia and corneal astigmatism. Trial registration None.

“…Complications were minimal and amenable to treatment. 7,[18][19][20][21][22][23] To our knowledge, this is the first report describing the performance of a foldable iris-fixated toric pIOL for the correction of myopic astigmatism in phakic eyes. Eyes with a spherical equivalent of À2.63 to À13.0 D were included.…”

“…The development and implementation of the Toric IOL provided surgeons with an alternative to correct astigmatism during phacoemulsification cataract surgery. Emerging studies have indicated high accuracy and efficacy of Toric IOL in correcting astigmatism compared to spherical IOLs plus limbal relaxing incisions ( 5 , 6 ). In the present study, comparable results regarding the efficiency of astigmatism correction and rotational stability were obtained.…”

“…In comparison with the abovementioned methods, Toric intraocular lenses (Toric IOL) are able to more precisely correct astigmatism. Numerous studies have demonstrated the efficacy of Toric IOL vs. spherical IOL plus limbal relaxing incisions in correcting astigmatism ( 5 , 6 ). According to a retrospective study performed by Sun et al ( 7 ), the mean post-operative refractive cylinder was smaller in the Toric IOL group compared with that in the group subjected to spherical IOL implantation combined with limbal relaxing incisions (P<0.05), suggesting its advantages in efficiency and precision.…”

The present prospective clinical observational study aimed to evaluate the efficacy of Toric intraocular lenses (IOL) to achieve rotational stability and astigmatism correction in eyes with high myopia. A total of 27 consecutive cataract patients (39 eyes) with pre-existing corneal astigmatism (1.5–3.5 D) were divided into two groups according to their refractive status: One group of 18 eyes with high myopia -(12.5–6.0 D) and another group consisting of 21 eyes with emmetropia or low myopia (−3.0–0.0 D). All eyes underwent cataract phacoemulsification surgeries by the same surgeon, with the implantation of an AcrySof® Toric IOL at the pre-designed degree. Uncorrected visual acuity, best corrected visual acuity and phoropter examination results were recorded at the 1st day, 1st week, 1st month and 3rd month after the surgery. By analyzing digital images from slim-lamp photography with a self-designed software, the rotational stability was observed. The contrast sensitivity was also measured. No significant difference in the baseline and post-operative residual astigmatism was identified between the two groups (P>0.05). In addition, no significant difference in the degree of rotation was observed between the two groups. All patients had significantly improved visual quality after the surgery (P<0.05). In conclusion, the present study observed an equal astigmatism-correction efficiency and rotational stability in the two groups. A second auxiliary spot-penetrating incision, removal of visco-elastic substances and tight adherence of the IOL to the posterior capsular membrane are essential for a successful surgery.
