Patient-reported quality of vision in a prospective randomized contralateral-eye trial comparing LASIK and small-incision lenticule extraction

Purpose: To compare patient-reported quality of vision and visual symptoms in participants undergoing laser in situ keratomileusis (LASIK) and small-incision lenticule extraction (SMILE).

Setting: Byers Eye Institute, Stanford University, Palo Alto, California.

Design: Prospective randomized contralateral-eye clinical trial.

Methods: Patients with myopia were randomized to receive wavefront-guided femtosecond LASIK in one eye and SMILE in the fellow eye. Participants reported the presence and severity of adverse visual symptoms through the Patient-Reported Outcomes With Laser In Situ Keratomileusis questionnaire and reported which eye had better vision at the preoperative and the postoperative 1-month, 3-month, 6-month, and 12-month visits. Results: 80 eyes of 40 participants were treated. There was no difference in the presence or severity of double vision, glare, halos, or starbursts between eyes that underwent LASIK or SMILE at each visit ( P ≥ .85 for each comparison). Scaled scores for the presence of visual symptoms improved from the preoperative visit to the postoperative month 12 visit for double vision (88 vs 97, P = .03), glare (77 vs 92, P = .02), halos (68 vs 87, P < .01), and starbursts (60 vs 86, P < .01). At the postoperative month 12 visit, 17 (46%) of 37 participants preferred the vision from the eye that underwent LASIK compared with 7 (19%) of 37 who underwent SMILE. The preferred eye was correlated with uncorrected distance visual acuity ( r = 0.52, P < .01). Conclusions: Rates of visual symptoms were similar for LASIK and SMILE, and visual symptoms improved with time. More patients preferred vision from the eye that underwent LASIK compared with SMILE.

Randomized and double-blind comparison of clinical visual outcomes of 2 EDOF intraocular lenses

Purpose: To assess and compare the visual disturbance profiles of 2 extended depth-of-focus (EDOF) intraocular lenses (IOLs).

Setting: Private practice (West Kootenays, British Columbia, Canada).

Design: Prospective, randomized, single-surgeon study.

Methods: This was a double-blind prospective study of 138 eyes (69 patients) that underwent bilateral implantation of 1 of 2 EDOF IOLs. Participants were randomized to either the Symfony group or the Vivity group. Outcome measures included Questionnaire for Visual Disturbances; binocular corrected distance visual acuities at distance (6 m), intermediate (66 cm), and near (40 cm); and refractive outcomes. Results: At 3 months postoperatively, 21 patients (60%) reported not experiencing glare in the Symfony group compared with 30 (88%) in the Vivity group, a difference of 28% ( P = .008). Reports of experiencing starbursts were also significantly different between the Symfony and Vivity groups (23 participants [66%] Symfony and 30 participants [88%] Vivity; P = .027). In addition, 12 participants (34%) reported “moderate” or “severe” starbursts in the Symfony group compared with 3 (9%) in the Vivity group, a difference of 25% ( P = .019). Visual acuities and refractive outcomes were similar between groups. Conclusions: Both EDOF lenses provide good visual outcomes at distance and intermediate with acceptable near vision. The Symfony group had increased reports of some visual disturbances, notably the frequency, severity, and bothersome Ness of starbursts and glare.

Vision and patient-reported outcomes with nondiffractive EDOF or neutral aspheric monofocal intraocular lenses

Purpose: To compare outcomes in patients who underwent cataract extraction with implantation of nondiffractive extended depth-of-focus (ND-EDOF; Alcon AcrySof Vivity) or neutral aspheric monofocal (Bausch & Lomb enVista) intraocular lenses (IOLs).

Setting: Academic medical center.

Design: Prospective single-center double-arm patient- and assessor-masked randomized controlled trial. Methods: Patients were randomized to receive either a ND-EDOF or monofocal IOL in both eyes, targeted for emmetropia. Uncorrected and corrected (CDVA) distance visual acuities, distance-corrected intermediate visual acuity (DCIVA), distance-corrected near visual acuity (DCNVA), level of spectacle independence, and severity of photic phenomena were assessed at 3 months postoperatively. Results: 56 patients were enrolled, of which 24 in the ND-EDOF group and 27 in the monofocal group completed follow-up. The binocular mean CDVA, DCIVA, and DCNVA were 20/20, 20/19, and 20/21 for the ND-EDOF IOL and 20/18 ( P = .188), 20/31 ( P < .001), and 20/30 ( P = .004) for the monofocal IOL, respectively. At intermediate, 88% of the ND-EDOF vs 30% of the monofocal patients had a binocular DCIVA of 20/25 or better ( P < .001). Moderate or severe glare occurred in 20.8% of ND-EDOF vs 7.4% of monofocal patients ( P = .228), whereas moderate or severe halos occurred in 16.7% of ND-EDOF vs 11.1% of monofocal patients ( P = .697). Conclusions: The ND-EDOF and monofocal IOLs provided similarly excellent distance vision. Patients implanted with the ND-EDOF IOL had 2 more lines of vision at both intermediate and near, and a greater proportion reported spectacle independence. Most patients in both groups reported low severity of photic phenomena.

Ten-year outcomes of pseudophakic mini-monovision correction of hyperopic presbyopia

Purpose: To evaluate long-term efficacy, safety, and spectacle independence after the treatment of hyperopic presbyopia with pseudophakic mini-monovision using standard monofocal intraocular lenses (IOLs) after bilateral cataract surgery.

Setting: Private practice in Barcelona, Spain.

Design: Retrospective, noncomparative case series.

Methods: Patients with hyperopic presbyopia underwent bilateral cataract surgery with pseudophakic mini-monovision using standard monofocal IOLs between 2008 and 2018. Main outcomes analyzed were uncorrected distance visual acuity (UDVA), uncorrected near distance visual acuity (UNVA), and rates of spectacle independence at postoperative day 1 (POD1), months 1, 6 and 12, and at 5 and 10 years (Y10) postoperatively. Results: The study enrolled 463 patients. Both UDVA and UNVA significantly improved postoperatively ( P < .05). The mean binocular UDVA improved from 0.47 ± 0.3 logMAR preoperatively to 0.096 ± 0.14 at POD1 to 0.16 ± 0.2 at Y10 ( P = .0033). The binocular UNVA was 0.05 logMAR at Y10, whereas in preoperative visits, all patients needed spectacles. The mean UDVA for the dominant eye ≤0.20 logMAR was achieved in 84.29% at the Y10. Self -reported and measured complete spectacle independence for near vision was achieved in 79.61% of patients at POD1 and 71.92% at Y10 postoperatively. For distance, respectively, in 86.29% of patients at POD1 and 78.43% at Y10. The achieved results were stable. No serious events were reported, as well as no photic phenomena. Conclusions: Pseudophakic mini-monovision in hyperopic presbyopes is a safe, effective, and low-cost approach for the long-term correction of presbyopia. It significantly reduces spectacle dependence and fulfils patients' expectations after bilateral cataract surgery.

Nd: YAG laser capsulotomy rates in the Netherlands: practice variation and association with physician practice styles

Purpose: To determine the practice variation in the rate of Nd:YAG laser capsulotomy within 1 year after cataract surgery and to identify possible associations with physician practice styles.

Setting: All hospitals and private clinics in the Netherlands.

Design: Retrospective observational study.

Methods: In the national medical claims database, we identified all laser capsulotomies performed in the Netherlands within a year after cataract surgery in the years 2016 and 2017. Centers with the lowest and highest percentages of Nd:YAG laser capsulotomies were interviewed on their physician practice styles related to the development of posterior capsule opacification. Results: The incidence of Nd:YAG laser capsulotomy varied between 1.2% and 26.0% in 2016 (median 5.0%) and between 0.9% and 22.7% in 2017 (median 5.0%). The rate of capsulotomy was highly consistent over time for each center (Pearson correlation coefficient, 0.89, P < .001). In general, ophthalmology centers with a high rate of Nd:YAG laser capsulotomy more often did not (routinely) polish the posterior lens capsule, performed cortex removal with coaxial irrigation/aspiration (I/A, instead of bimanual), and more often used hydrophilic intraocular lenses (IOLs) (compared with only using hydrophobic IOLs). Conclusions: We found a significant practice variation in performing Nd:YAG laser capsulotomy within 1 year after cataract surgery in the Netherlands. Routinely polishing the posterior capsule, using bimanual I/A, and the use of hydrophobic IOLs are associated with a lower incidence in Nd:YAG laser capsulotomy. Incorporating these practice styles may lower the practice variation and thus prevent added medical burden for the patient and decrease costs.
