Aim?To evaluate central macular thickness (CMT) following improved vision and stereoacuity in pediatric patients after medical intervention. Method?We enrolled children having refractive errors, squint, or cataract. Anterior and posterior segment examinations were done with stereoacuity evaluated. We subjected all eyes for Spectral domain optical coherence tomography (SD-OCT) and measured CMT. After appropriate treatment, stereoacuity and OCT were evaluated again after 3 months. Result?Here, we enrolled 229 children with mean age 10.6???4.5 and found significant improvement in vision and stereoacuity after treatment (p?

PurposeTo assess spectacle independence and patient satisfaction with pseudophakic mini-monovision in patients undergoing routine bilateral cataract surgery with implantation of an aspherical aberration-free intraocular lens (Akreos AO, Bausch and Lomb, USA).MethodsThis study was a retrospective analysis that included 60 eyes of 30 consecutive patients between 2016 and 2018. The included patients had undergone sequential bilateral routine phacoemulsification after choosing the mini-monovision option. Test for ocular dominance was done using a sighting test. Emmetropia was aimed at in the dominant eye, while in the non-dominant eye the aim was myopia between −1 D and −1.5 D. The main outcome parameters were uncorrected distance visual acuity (UDVA), uncorrected near visual acuity (UNVA), and data reported from a questionnaire given to the patients at 3 months postoperative visit.ResultsThe study included 60 eyes of 30 consecutive patients. The mean binocular UDVA was 0.09 ± 0.07 logMAR. Twenty-eight patients (93%) had binocular UDVA of 0.2 logMAR or better. The mean binocular uncorrected intermediate distance visual acuity (at 65 cm) was 0.16 ± 0.12 logMAR. Twenty-six patients (87%) had binocular uncorrected intermediate distance visual acuity of 0.2 logMAR or better. The mean binocular UNVA (at 35 cm) was 0.30 ± 0.21 logMAR. Fourteen patients (47%) had binocular UNVA of 0.2 logMAR or better. The patients score in the questionnaire was significantly higher in far and intermediate vision than near vision (p = 0.022). The patients score was significantly higher in day vision than night vision (p = 0.031). The mean overall patient satisfaction was good (9.1 ± 1.54). Twenty-eight patients (93%) reported high spectacle independence for far vision (score 8, 9, or 10).ConclusionPseudophakic mini-monovision shows good results for spectacle independence and high patient satisfaction. It is a safe and inexpensive option after bilateral cataract surgery for correcting distance and intermediate vision. However, it might show lower results with near and night vision which is generally acceptable. Using aberration-free monofocal IOL allows for the residual normal positive corneal aberration that may augment the effect of monovision.

“…This does not have seem to make any difference in the outcomes, as it was shown in the earlier published studies that patient satisfaction as well as the visual results of crossed monovision were no different from conventional monovision. [26][27][28]…”

Title Visual and refractive outcomes and patient satisfaction following implantation of monofocal intraocular lens in one eye and ERV intraocular lens in the contralateral eye with mini-monovision. Purpose To evaluate the outcomes following implantation of monofocal intraocular lens in one eye and ERV intraocular lens in the contralateral eye with mini-monovision. Methods Twenty-five subjects underwent bilateral cataract surgery, wherein the dominant eye received monofocal Tecnis-1 IOL, while in the contralateral eye received the Tecnis Symphony ERV IOL. The dominant eye was targeted for emmetropia and the non-dominant eye for myopia of −0.50 to −0.75D. Binocular uncorrected and corrected distance (UDVA, CDVA), intermediate (UIVA, CIVA), and near (UNVA, DCNVA) visual acuity; reading speeds, defocus curve and contrast sensitivity were studied at 6 months post-operatively. Results At 6 months post-operatively the mean binocular UDVA, CDVA, UNVA and DCNVA were 0.007±0.07, −0.13±0.06, 0.26±0.09 and 0.44±0.10 LogMAR, respectively. Binocular UIVA and DCIVA at 60 cm were 0.22±0.10 and 0.18±0.08 LogMAR and at 80 cm was 0.16±0.11 and 0.15±0.10 LogMAR, respectively. Mean uncorrected reading speeds evaluated with SRD at 40, 60 and 80 cm were 114.4±6.9, 126.4±7.9 and 123.16±5.8 words per minute. Contrast sensitivity values did not show significant difference for any spatial frequency tested. At 6 months, only 12% (3 patients) reported mild halos. Spectacle independence satisfaction scores were 96%, 100% and 88% for distance, intermediate and near. Conclusion Implantation of monofocal intraocular lens in one eye and ERV intraocular lens in the contralateral with mini-monovision resulted in good outcomes for far and intermediate, and satisfactory outcomes for near vision, with good tolerance to mini-monovision at the end of 6 months.
