“…A meta-analysis of studies that included LRIs made with both manual and femtosecond laser systems suggests that the likelihood of achieving a residual refractive cylinder of ≤0.50 D is higher with a toric IOL. 17 There are limitations to this study. Perhaps most importantly, it was difficult to obtain a significant sample size of matched patients without a large range of follow-up times, but it was felt that the tradeoff for good biometric matches was important.…”

Purpose To compare uncorrected and best-corrected visual acuity, low contrast acuity, residual refraction and ocular biometry after low cylinder power toric intraocular lens (IOL) or non-toric IOL implantation. Patients and Methods This was a non-interventional comparative study of visual outcomes after uncomplicated cataract or refractive lens exchange surgery with either a low cylinder (Low_Cyl) or non-toric (Non_Toric) IOL of similar design implanted (AcrySof ® T2 IQ Toric IOL and AcrySof ® IQ IOL). Subjects in both groups had to have been eligible for the low cylinder IOL based on biometry. They had to have uncorrected distance visual acuity (UDVA) of 20/32 (0.2 logMAR) or better at the time of their single diagnostic study visit. Clinical evaluation included the manifest refraction, visual acuity (VA), low contrast VA and ocular biometry. Results A total of 94 eyes were enrolled, 51 Low_Cyl and 43 Non_Toric. The mean manifest refractive cylinder was statistically significantly lower (~0.25 D) in the Low_Toric group (p < 0.01) and significantly more eyes had 0.25 D or less of refractive cylinder in that group (p = 0.03). The orientation of the preoperative anterior corneal astigmatism was a significant cofactor, with the difference between groups more evident when astigmatism was against the rule. Uncorrected high contrast visual acuity was statistically significantly better in the Low_Toric group (p = 0.02) as was the percentage of eyes with 20/20 visual acuity (p = 0.05). Uncorrected low contrast visual acuity was not statistically significantly different in mesopic or photopic conditions. Conclusion The low cylinder power toric IOL provided better uncorrected visual acuity and lower residual refractive cylinder than a similar non-toric IOL after cataract surgery.

Key Points Question What is the association between vision impairment, eye diseases, or ophthalmic interventions and quality of life? Findings In this cross-sectional study of systematic reviews, vision impairment and eye diseases were associated with lower quality of life. More than half of the ophthalmic interventions included had a positive association with quality of life. Meaning The associations of quality of life with vision impairment and the improvements in quality of life with ophthalmic interventions support efforts to improve access to ophthalmic treatments globally to reach the millions of people affected by eye disease each year.

“…[ 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.
