PurposeTo evaluate whether the presence of dome-shaped macula (DSM) is a protective factor for visual acuity after cataract surgery in patients with high myopia.MethodsIncluded were 891 highly myopic cataract eyes (600 patients) that were examined by optical coherence tomography (OCT) through the central fovea and underwent cataract surgery in our hospital. DSM was defined as an inward bulge >50 µm in horizontal or vertical OCT sections. The incidences of various maculopathies were compared between eyes with and those without DSM. The influences of age, sex, eye laterality, axial length and DSM on postoperative visual acuity were evaluated by multivariate linear regression.ResultsOf the 891 eyes, 123 (13.8%) had DSM. There was a greater association of DSM with extrafoveal retinoschisis (RS) than with other vision-threatening complications such as foveal RS and choroidal neovascularisation. In addition to axial length and age, sex was associated with the presence of DSM (p=0.016). In bilateral high myopia, the incidence of DSM increased with the degree of anisometropia and was more common in the longer eye of patients with anisometropia. Younger age, male sex, shorter axial length and the presence of DSM were associated with better postoperative visual acuity in highly myopic cataract eyes (β=0.124, p=0.002; β=0.142, p<0.001; β=0.275, p<0.001 and β=−0.088, p=0.038, respectively).ConclusionAssociated with fewer visual threatening macular complications, presence of DSM may be a protective factor for visual function after cataract surgery in highly myopic eyes.

Abstract Objective The study aimed to evaluate the safety and efficacy of resident surgeons performing femtosecond laser assisted cataract surgery (FLACS). Methods A retrospective chart review was conducted at the University of Wisconsin-Madison from postgraduate year four residents performing FLACS between 2017 and 2019. Data were also collected from residents performing manual cataract surgery, and attending surgeons performing FLACS for comparison. Recorded data included patient demographics, pre- and postoperative visual acuity, pre- and postoperative spherical equivalent, nuclear sclerotic cataract grade, ocular and systemic comorbidities, intraocular lens, duration of surgery, cumulative dissipated energy (CDE), and intraoperative and postoperative complications. Results A total of 90 cases were reviewed with 30 resident manual cases, 30 resident FLACS cases, and 30 attending FLACS cases. Resident manual (25.5 ± 6.8 minutes) and resident FLACS (17.5 ± 7.1 minutes) cases took a significantly longer time to complete compared with attending FLACS cases (13.6 ± 4.4 minutes; p < 0.001). There was higher CDE in resident FLACS and resident manual cases compared with attending FLACS cases, but the difference was not statistically significant (p = 0.06). Postoperative visual acuity was not statistically different at 1-day and 1-month after surgery among the three groups. Resident FLACS complications, which included one case requiring an intraoperative suture to close the wound, two cases with intraoperative corneal abrasions, two cases with postoperative ocular hypertension, and one case with cystoid macular edema, were not significantly greater than attending FLACS complications (p = 0.30). Conclusion The FLACS performed by resident surgeons had comparable visual acuity outcomes to FLACS performed by attending surgeons, and to manual cataract surgery performed by resident surgeons. However, resident FLACS cases took significantly longer time to complete, and they were associated with a higher CDE and minor complication rate compared with attending FLACS cases. Introducing advanced technologies into surgical training curricula improves resident preparedness for independent practice, and this study suggests FLACS can be incorporated safely and effectively into resident education.

BackgroundWe investigated glaucoma related adverse events, predictors and impact at 5 years following surgery in the IoLunder2 cohortMethodsPopulation based observational cohort study of children undergoing cataract surgery aged 2 years or under between January 2009 and December 2010. Glaucoma was defined using internationally accepted taxonomies based on the consequences of elevated intraocular pressure (IOP). Glaucoma related adverse events were any involving elevated IOP. Multivariable analysis was undertaken to investigate potential predictors of secondary glaucoma with adjustment for within-child correlation in bilateral cataract. Unilateral and bilateral cataract were analysed separately.ResultsComplete follow-up data were available for 235 of 254, 93% of the inception cohort. By 5 years after primary cataract surgery, 20% of children with bilateral cataract and 12% with unilateral had developed secondary glaucoma. Glaucoma related complications had been diagnosed in 24% and 36% of children, respectively. Independent predictors of glaucoma were younger age at surgery (adjusted OR for reduction of week in age: 1.1, 95%C I 1.1 to 1.2, p<0.001); the presence of significant ocular comorbidity (adj OR 3.2, 95% CI 1.1 to 9.6, p=0.01); and shorter axial length (adj OR for each mm 1.7, 95% CI 10.0 to 1, p=0.05) for bilateral cataract. Shorter axial length was the single independent factor in unilateral disease (adj OR 9.6, 95% CI 1.7 to 52, p=0.009)ConclusionsBoth younger age at surgery (the strongest marker of ocular ‘immaturity’) and smaller ocular size (a marker of both immaturity and developmental vulnerability) can be used to identify those at greatest risk of glaucoma due to early life cataract surgery.

Purpose: To develop a photographic classification for cilioretinal arteries and to investigate its association with myopic macular degeneration (MMD).Methods: One thousand six hundred ninety-two highly myopic eyes of 1,692 patients were included. The presence of a cilioretinal artery was determined by fundus photographs, and a photographic classification was proposed. MMD was classified according to the International META-PM Classification. Associations of the cilioretinal artery and its classifications with MMD and visual acuity were analyzed.Results: Of the eyes tested, 245 (14.5%) had a cilioretinal artery. The cilioretinal arteries were classified into four categories (temporal “cake-fork,” 35.92%; temporal “ribbon,” 53.47%; “multiple,” 6.53%; “nasal,” 4.08%) and 3 distributions based on whether its visible branches reached the central foveal area. Eyes with cilioretinal arteries had significantly less MMD of grade ≥3 and better visual acuity than those without (P &lt; 0.01). Multiple linear regression analysis showed that younger age, male sex, shorter axial length, and the presence of a cilioretinal artery were associated with better visual acuity in highly myopic eyes (all P &lt; 0.05). The “nasal” category presented more MMD with grade ≥3 and worse visual acuity than the other categories (P &lt; 0.05), whereas the “multiple” category contained no eyes with MMD grade ≥3. The cilioretinal arteries reaching the central foveal area showed less MMD of grade ≥3 and better visual acuity than those not (P &lt; 0.05).Conclusions: We propose a photographic classification for cilioretinal arteries that has good clinical relevance to visual functions. The cilioretinal artery may potentially afford protection against MMD.

Vitreous Loss

Purpose. The purpose of this study is to find prognostic factors associated with low visual acuity in patients experiencing vitreous loss during cataract surgery. Methods. A retrospective, noncomparative, interventional, case study of patients experiencing vitreous loss during cataract surgery. Data collected included demographics, best corrected visual acuity (BCVA), axial length (AL), presence of ocular comorbidity affecting central vision, timing of intraocular lens (IOL) implantation, position of the implanted lens, and the presence of corneal sutures. Low visual outcome was defined as BCVA < 20/40. Results. Overall, 179 patients (60.3% males) with a mean age of 73 ± 12 years and axial length of 23.5 ± 1.3 mm with a mean follow-up of 12 ± 13 months were included. In multivariable logistic regression analysis, low visual outcome was independently associated with persisting postoperative complications (OR 6.25, 95% CI 1.378–30.9), preexisting ocular comorbidities (OR 4.45, 95% CI 1.1–18.00), and secondary intraocular lens (IOL) implant (OR 10.36, 95% CI 1.8–60.00). Conversely, pars plana vitrectomy (PPV) for dislocated fragments of lens material, age > 70 years, gender, axial length, degree of surgeon, corneal suturing, and anterior chamber lens implantation were not found to have significant associations with low visual outcomes ( P > 0.05 ). Conclusions. Low visual outcome after vitreous loss during cataract surgery was associated with ocular comorbidities, secondary IOL implantation, development of cystoid macular edema, and additional surgical complications.

The Impact

Purpose. To determine the effects of cataract surgery on contrast visual acuity and retinal sensitivity in patients with retinitis pigmentosa. Methods. Retinal sensitivity and contrast visual acuity were determined by microperimetry (MAIA) and contrast sensitivity acuity tester (CAT-CP), respectively, before and after cataract surgery. The significance of the correlations between visual acuity, retinal sensitivity, contrast visual acuity, improvements after surgery, and macular structure before and after cataract surgery was determined. Results. Retinal sensitivity and contrast visual acuity were significantly improved after cataract surgery. The correlations among postoperative visual acuity, postoperative retinal sensitivities, and preoperative ellipsoid zone length were significant. The postoperative retinal sensitivity of the central 10° and the ellipsoid zone length was particularly significantly correlated. Preoperative contrast visual acuity and the amount of improvement and preoperative retinal sensitivity and the amount of improvement were significantly negatively correlated. The contrast visual acuity under both the 100% and 10% photopic and mesopic conditions improved significantly after cataract surgery. Conclusions. Cataract surgery in retinitis pigmentosa patients with preserved ellipsoid zones significantly improved retinal sensitivity and contrast visual acuity. Cataract surgery can be expected to improve retinal sensitivity and contrast visual acuity under various conditions, even if preoperative visual parameters are low, as long as the ellipsoid zone is preserved.
