Background: The purpose of this case series is to report the one-year outcomes of small incision lenticule extraction (SMILE) using the VisuMax® femtosecond laser.
Methods: Two hundred and six patients were recruited for this retrospective, single center study at TRSC International LASIK Center in Bangkok, Thailand. Patients underwent SMILE, whereby an intrastromal lenticule was cut using a femtosecond laser and then manually extracted without the need for flap creation. Outcome measures included refraction, visual acuity and contrast sensitivity evaluation. Patients were treated and followed for one year.
Results: SMILE for the correction of low to high myopia was performed on 347 eyes of 206 patients. The mean preoperative spherical equivalent was -4.96 ± 1.88 diopters (D). On the first day following surgery, for eyes with a plano target refraction (99.14 % of all eyes), uncorrected distance visual acuity (UDVA) was 20/20 or better in 90 % of eyes. At the one week postoperative exam, the mean spherical equivalent was 0.01 ± 0.36 D and UDVA was 20/20 or better in 84 % of eyes. After one year follow-up, no eyes showed loss of 2 or more lines of visual acuity and 31 % of eyes gained one or more lines. The photopic contrast sensitivity of SMILE treated eyes at 12 and 18 cycles per degree (cpd) improved from 1.59 and 0.94 preoperatively to 1.6 and 0.98, respectively, after one year.
Conclusions: In this series, SMILE using the VisuMax® femtosecond laser demonstrated that after one year it is an effective, predictable and safe minimally invasive corneal refractive procedure.

Ahmed glaucoma valve implant for refractory glaucoma in children: A systematic review and meta-analysis.
Sci Prog

School of Medicine, University of Electronic Science and Technology of China, Chengdu, China.
Purpose: The aim of this study was to evaluate the efficacy and safety of the Ahmed glaucoma valve in pediatric patients with refractory glaucoma.
Methods: A comprehensive literature search was conducted across multiple major databases, including PubMed, Embase, the Cochrane Library of Systematic Reviews, Science Direct, China's National Knowledge Infrastructure, and the Wanfang database. We retrieved studies published before December 2022 that met the inclusion criteria, including clinical controlled trials (randomized controlled trials) and clinical noncontrolled trials (non-randomized controlled trials) on the use of Ahmed glaucoma valve in pediatric patients with refractory glaucoma.
Background: Lens implantation becomes a major concern in patients lacking posterior capsular support, but various methods are available for rehabilitation. In such patients, scleral-fixated intraocular lens (SFIOL) implantation is preferred due to its fewer complications and better simulation of the natural lens position. In this non-randomized retrospective clinical study, we aimed to assess visual outcomes after sutureless SFIOL implantation in aphakic patients and factors affecting visual outcomes.

Purpose: This study highlights the feasibility of femtosecond laser-assisted large-diameter lamellar corneal-limbal keratoplasty and its efficacy in the treatment of ocular surface failure caused by bilateral ocular chemical injury.
Observations: The series included 3 patients with ocular surface failure caused by bilateral ocular chemical burns. After dissection of the host cornea, a femtosecond laser-assisted large-diameter lamellar corneoscleral button, with varying thickness of 250-400 μm, was sutured to the recipient bed.
Smaller-incision new-generation implantable miniature telescope in late-stage age-related macular degeneration: 6 month outcomes.

Ophthalmology Unit, Fondazione Policlinico Universitario A. Gemelli IRCCS, Rome, Italy.
Purpose: To evaluate the intermediate-term visual and safety outcomes of the small-incision second-generation implantable miniature telescope (SING IMT) in patients with late-stage age-related macular degeneration (AMD) at 6 months post-surgery.
Design: Retrospective cohort study.
Methods: Medical records of patients implanted with the SING IMT at two sites in Italy were reviewed.
Purpose: To assess the safety and efficacy of a modified suprachoroidal silicone tube (SST) shunt in patients with primary open-angle glaucoma (POAG) and pseudo-exfoliative glaucoma (PXG) in this experimental study.
Methods: In this single-center, retrospective longitudinal data analysis 66 eyes of 59 patients having POAG and PXG were included and treated with modified SST shunt in combination with cataract or as a stand-alone procedure. Pre- and postoperative intraocular pressure (IOP), best corrected visual acuity (BCVA), C/D ratio and ocular adverse events (AEs) were assessed in all participants.
