“…Although 1 study did not show worsening of ERM after cataract surgery, others have described progression in as many as 45% of cataract surgery patients over a 3-year period . In our study, 7.1% of eyes with ERM (vs 2.7% of reference eyes) assessed at 4 to 12 weeks postoperatively demonstrated VA worsening by 0.30 logMAR or more.…”

IMPORTANCE Primary epiretinal membrane (ERM) is a common retinal disorder with a prevalence of 4% to 18.5%. Although ERM and cataracts commonly occur together, to our knowledge, no studies have investigated the outcome of cataract surgery alone in this setting. OBJECTIVE To analyze the visual outcome and cystoid macular edema risk with cataract surgery in eyes with primary ERM. DESIGN, SETTING, AND PARTICIPANTS In this retrospective clinical database study, data were collected from July 2003 to March 2015 from 8 locations in the United Kingdom. Cataract surgery data of 217 557 eyes were extracted from the electronic medical record of the UK National Health Service. After exclusion of 57 561 eyes with combined surgery, prior vitrectomy, copathology, and complications, 812 eyes with primary ERM and 159 184 reference eyes were analyzed. MAIN OUTCOMES AND MEASURES We report on visual acuity (VA), the incidence of cystoid macular edema, and the need for ERM surgery. RESULTS The mean (SD) age of patients in the ERM group was 73.7 (9.23) years, and 395 of 812 were men (46.8%). The mean (SD) age of patients in the reference group was 74.4 (12.19) years, and 65 265 of 159 184 were men (41%). Epiretinal membrane eyes assessed at 4 to 12 weeks postoperatively gained 0.27 (0.32) logMAR (approximately 3 Snellen lines), with 200 of 448 (44.6%) improving by 0.30 logMAR or more (Ն3 Snellen lines) and 32 of 448 (7.1%) worsening by 0.30 logMAR or more. Reference eyes gained a mean (SD) of 0.44 (0.26) logMAR (approximately 4 Snellen lines), with 48 583 of 77 408 (62.8%) improving by 0.30 logMAR or more and 2125 of 77 408 (2.7%) worsening by 0.30 logMAR or more. Although all eyes with preoperative VA of 20/40 or less improved, only reference eyes with preoperative VA of more than 20/40 showed improvement. Cystoid macular edema developed in 57 of 663 ERM eyes (8.6%) (95% CI, 6.69-10.98) and 1731 of 125 435 reference eyes (1.38%) (95% CI, 1.32-1.45) (P < .001). Epiretinal membrane surgery was performed in 43 of 663 (6.5%) ERM eyes. CONCLUSIONS AND RELEVANCE On average, VA improved 0.27 logMAR (approximately 3 Snellen lines) in eyes with ERM. Eyes with ERM and VA of 20/40 or less showed more benefit after cataract surgery than those with better preoperative vision. However, compared with eyes without ERM, higher rates of cystoid macular edema and a lower postoperative VA gain were noted.

“…1 The dominant eye plays an important role in binocular vision and the clinical diagnosis and treatment of ophthalmologic disorders. 2 Treatments include laser in situ keratomileusis (LASIK), multifocal intraocular lens implantation, and other refractive surgeries that use monocular vision correction for the treatment of presbyopia, strabismus, amblyopia, and nystagmus. 3,4 Previous controversy remains regarding where to center corneal refractive procedures to maximize visual outcomes.…”

“…A dominant eye is the eye from which a person prefers to receive visual input 1 , 2 . The dominant eye plays an important role in binocular visual function and clinical diagnosis and treatment of ophthalmologic disorders, such as LASIK and multifocal intraocular lens implantation and other refractive surgeries using monocular vision correction for the treatment of presbyopia, strabismus, amblyopia, nystagmus, and other clinical applications 3 , 4 , 5 .…”

Purpose:To investigate the differences between dominant and nondominant eyes in a predominantly young patient population by analyzing the angle kappa, pupil size, and center position in dominant and nondominant eyes. Methods: A total of 126 young college students (252 eyes) with myopia who underwent femtosecond laser-combined LASIK were randomly selected. Ocular dominance was determined using the hole-in-card test. The WaveLight ALLEGRO Topolyzer was used to measure the pupil size and center position. The offset between the pupil center and the coaxially sighted corneal light reflex (P-Dist) of the patients was recorded by the X and Y axis eyeball tracking adjustment program of the WaveLight Eagle Vision EX500 excimer laser system.The patient’s vision [uncorrected distance visual acuity (UDVA), best corrected visual acuity (BCVA)], refractive power [spherical equivalent (SE)] were observed preoperatively, 1 week, 4 weeks, and 12 weeks postoperatively, and a quality of vision (QoV) questionnaire was completed. Results: Ocular dominance occurred predominantly in the right eye (right vs. left: (178) 70.63% vs. (74) 29.37%; P < 0.001). The P-Dist was 0.202 ± 0.095 mm in the dominant eye and 0.215 ± 0.103 mm in the nondominant eye (P = 0.021). The horizontal pupil shift was −0.07 ± 0.14 mm in dominant eyes and 0.01 ± 0.13 mm in nondominant eyes (P = 0.001) (the temporal displacement of the dominant eye under mesopic conditions). The spherical equivalent was negatively correlated with the P-Dist (r = −0.223, P = 0.012 for the dominant eye; and r = −0.199, P = 0.025 for the nondominant eye). At 12 weeks postoperatively, the safety index (postoperative BDVA/preoperative BDVA) of the dominant and non-dominant eyes were 1.20 (1.00, 1.22) and 1.20 (1.00, 1.20), respectively, and the efficacy index (postoperative UDVA/preoperative BDVA) were 1.00 (1.00, 1.20) and 1.00 (1.00, 1.20), respectively; the proportion of residual SE within ± 0.50D was 98% and 100%, respectively. Conclusions: This study found that ocular dominance occurred predominantly in the right eye. The pupil size change was larger in the dominant eye. The angle kappa of the dominant eye is smaller than that of the nondominant eye and the pupil center of the dominant eye is slightly shifted to the temporal side under mesopic conditions. The correction of myopia in the dominant and nondominant eyes has good safety, efficacy, and predictability in the short term after surgery, and has good subjective visual quality performance after correction. We suggest adjusting the angle kappa percentage in the dominant eye to be lower than that of the nondominant eye in individualized corneal refractive surgery to find the ablation center closest to the visual axis.

Ocular dominance, coexistent retinal disease, and refractive errors in patients with cataract surgery

Abstract: It is mandatory to recognize phorias, tropias, anisometropia, and amblyopia when planning cataract surgery. Visual potential, ocular dominance, refractive errors, and other retinal comorbidities influence cataract surgery planning and outcome.
