“…Vision correction to prevent the development of amblyopia is often initiated before age 7 or 8 years, making it ineligible for inclusion in our review. 33 The potential impact of astigmatism on myopia progression was also out of the scope of this systematic literature review. These fields are of huge clinical importance, and future review should focus on this perspective and pediatric population (younger than 18 years).…”

“…There is no consensus on a standard classification of astigmatism in the published literature. Although some classify astigmatism as mild (<1.50 D), moderate (1.50 to 2.00 D), and severe (>2.0 D), 33 others classify it as mild (<1.50 D), moderate (1.50 to 2.50 D), and significant/severe (>2.50 D) 34,35 . This review presents astigmatism outcomes for mild, moderate, and significant astigmatism, adhering to the classification based on previously published studies 34,35 .…”

SIGNIFICANCE This is the first literature review to report the epidemiology, patient burden, and economic burden of astigmatism in the general adult population. The unmet needs of astigmatism patients with coexisting ocular conditions (cataract, glaucoma, dry eye, presbyopia, or macular degeneration) and risks associated with untreated astigmatism are also reviewed and reported. PURPOSE This study aimed to identify, report, and summarize the published literature on epidemiology, patient burden, and economic burden of astigmatism using a systematic literature review. METHODS MEDLINE, EMBASE, and Cochrane Library databases were searched (January 1996 to May 2021). Search results were limited to the English language. Proceedings (2018 to 2021) from ophthalmology congresses were searched along with gray literature using the Google Scholar platform. RESULTS The literature search yielded 6804 citations, of which 125 met the inclusion criteria (epidemiology, 68; patient burden, 60; economic burden, 6). Astigmatism prevalence in the general population varied from 8 to 62%, with higher rates in individuals 70 years or older. The prevalence of with-the-rule astigmatism was higher in individuals 40 years or younger, whereas rates of against-the-rule and oblique astigmatism increased with age. Astigmatic patients experienced decreased vision quality, increased glare (53 to 77%), haloes (28 to 80%), night-time driving difficulties (66%), falls, and spectacle dependence (45 to 85%). Astigmatic patients performed vision-related tasks slower (1 D, 9% slower; 2 D, 29% slower) and made more errors (1 D, 38% more errors; 2 D, 370% more errors) compared with fully corrected individuals. In cataract patients with astigmatism, the annual mean per-patient productivity loss costs ranged from €55 ($71) to €84 ($108), and mean informal care costs ranged from €30 ($39) to €55 ($71) with a mean of 2.3 to 4.1 hours spent on informal care. CONCLUSIONS Uncorrected astigmatism decreases patients' vision-related quality of life, decreases productivity among working-age adults, and poses an economic burden on patients and their families.

PurposeTo evaluate the visual and refractive outcomes of astigmatic cataract patients following opposite clear corneal incision (OCCI) combined with rotationally asymmetric multifocal intraocular lens (IOL) implantation.SettingDepartment of Ophthalmology, Zhongshan Hospital (Xiamen), Fudan University, People’s Republic of China.DesignRetrospective cohort study.MethodsThis study comprised 58 cataract eyes of 54 patients with corneal astigmatism who underwent phacoemulsification and rotationally asymmetric multifocal IOL implantation which received either OCCI (OCCI group) or a single clear corneal incision (SCCI group). The follow-up period was 3 months after surgery. Distance, intermediate and near visual acuity, refractive outcomes, and corneal anterior keratometry were compared between the two groups. Vector analysis was used to evaluate astigmatism correction.ResultsThree months after surgery, the distance, intermediate and near visual acuity, and sphere remained comparable between the two groups, but a significant difference was detected in residual astigmatism and anterior corneal keratometric astigmatism. In the OCCI group, the residual astigmatism and keratometric astigmatism were −0.60 ± 0.29 D and 0.59 ± 0.28 D, respectively, which were lower than those in SCCI groups (−1.18 ± 0.47 D and 1.15 ± 0.45 D, both p < 0.05). In vector analysis, the difference vector (DV), angle of error (AoE), absolute AoE, index of success (IoS) and correction index (CI) were statistically significantly different between the two groups (p < 0.05).ConclusionOCCI combined with rotationally asymmetric multifocal intraocular lens implantation showed predictable and desirable efficacy in treating cataract patients with astigmatism.

Purpose To compare toric intraocular lens (IOL) implantation versus monofocal (Eyhance) IOL with paired corneal incisions for correction of low-grade astigmatism after phacoemulsification. Patients and methods A retrospective comparative study included 30 patients with low-grade astigmatism (−0.75 to −1.50 D) who underwent phacoemulsification: group 1 underwent toric IOL implantation (TECNIS toric) and group 2 underwent enhanced monofocal IOL (TECNIS Eyhance) with paired corneal incision along steep corneal meridian. Best-corrected visual acuity, astigmatism power, and axis were assessed preoperatively and 3 months postoperatively. Vector analysis of astigmatism was done using the Alpins method. Results The mean postoperative residual astigmatism was significantly lower in group 1 versus group 2 (−0.357±0.128 and −0.538±0.225 D, respectively; P=0.015). A significantly higher decrease in astigmatism was noted in group 1 (−0.93±0.18 and −0.38±0.69 D, respectively; P=0.006), with no significant difference in postoperative visual acuity. Paired comparison revealed significant decrease in astigmatism (P<0.0001 in group 1 and 0.04 in group 2) and improvement in uncorrected visual acuity (P<0.0001 for both groups). A significantly higher percentage of success was noted in group 1 (P=0.017), with a higher difference vector in group 2 (P=0.008). Conclusion Our results suggest that both toric IOL and paired corneal incision are efficient methods for postoperative astigmatism correction and achieving postoperative spectacle independence in patients with low-grade astigmatism. Toric IOL is superior in reducing postoperative astigmatism, reflecting more consistent results. The recommendation of IOL type and astigmatism correction should be tailored according to the patient's requirements, especially with the expanded need for good intermediate vision for everyday tasks that may benefit from enhanced IOLs.
