Purpose: To evaluate the safety of the corneal inlay removal procedure and the reversibility of visual acuities, corneal topography, and corneal biomicroscopy changes in a series of cases.
Methods: Ten cases implanted with one of three versions of the AcuFocus Kamra Inlay (ACI 7000, 7000T, and 7000PDT; AcuFocus, Inc., Irvine, CA) were followed for a minimum of 6 months after corneal inlay removal.
Results: The reason for removal was related to subjective dissatisfaction with visual symptoms (8 of 10 patients) such as night glare, photophobia, starburst, blurry vision, and halos. One case of removal was related to inadvertent thin flap and the final case was related to insufficient near vision. Mean uncorrected distance visual acuity (UDVA) and uncorrected near visual acuity (UNVA) was 0 ± 0.1 logMAR (Snellen 20/20) and 0.5 ± 0.2 logMAR (Snellen 20/40), respectively, preoperatively and 0.1 ± 0.1 logMAR (Snellen 20/25) and 0.5 ± 0.1 logMAR (Snellen 20/63), respectively, 6 months after corneal inlay removal. Mean corrected distance visual acuity (CDVA) and corrected near visual acuity (CNVA) was 0 ± 0.1 logMAR (Snellen 20/20) and 0 ± 0.1 logMAR (Snellen 20/20), respectively, preoperatively and 0 ± 0.1 logMAR (Snellen 20/20) and 0.1 ± 0.1 logMAR (Snellen 20/25), respectively, 6 months after corneal inlay removal. Mean root mean square (RMS) higher-order aberration (HOA) was 0.50 ± 0.12 (range: 0.30 to 0.70) preoperatively and 0.69 ± 0.14 (range: 0.48 to 0.95) 6 months after corneal inlay removal (P < .8). Weak positive correlation was found between Δt Implant-Removal (Δt I-R), RMS spherical, coma, and HOA at 6 months (Δt I-R vs RMS spherical was r = 0.2, r(2) = 0.5, P < .7; Δt I-R vs RMS coma was r = 0.8, r(2) = 0.6, P < .3; and Δt I-R vs HOA r = 0.8; r(2) = 0.6, P < .9).
Conclusion: This study suggests that after removal of the corneal inlay, corneal topography and corneal aberrometry are not permanently affected. In more than 60% of patients, CNVA, CDVA, UNVA, and UDVA were similar to the preoperative value.

Purpose: Formation of a full thickness macular hole (FTMH) after vitrectomy is rare. The aim of this study was to describe risk factors, clinical course, anatomical and functional prognosis of secondary FTMH development following surgery for primary rhegmatogenous retinal detachment (RRD).
Methods: Retrospective study.

Purpose: To assess the 12-month outcomes in subjects developing macular neovascularization (MNV) during intravitreal avacincaptad pegol (IVA) treatment for geographic atrophy (GA) secondary to age-related macular degeneration (AMD).
Methods: This research was conducted as a case-controlled, retrospective study of AMD subjects undergoing IVA treatment for GA from two private practice institutions. Subjects were divided into 1) a Study Group of patients who developed MNV and then underwent anti-vascular endothelial growth factor (VEGF) therapy during the study period, and 2) a Control Group of patients who were complication-free during the study period.

Purpose: To assess the effectiveness of split-thickness amniotic membrane (SAM) grafts in achieving closure of refractory or large macular holes (MH).
Methods: This retrospective study reviewed data from patients who underwent surgical repair of MHs using SAM grafts between January 2019 and December 2023. Key parameters, including best-corrected visual acuity (BCVA) and MH size, were evaluated both preoperatively and postoperatively.

To evaluate visual acuity improvement and identify contributing factors in patients with severe keratitis affecting both virgin and transplanted corneas, treated at a hospital. A retrospective analysis was conducted on 497 patients with unilateral corneal ulcers treated at a tertiary referral center between 2008 and 2023. Data included distance (BCVA) and near best-corrected visual acuity at initial presentation and at discharge, treatments before hospital admission, demographic details, risk factors, clinical signs and symptoms, ancillary test results, and management strategies.

Methods: This retrospective case series enrolled 25 eyes with high astigmatism that underwent SMILERO surgery. Uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), uncorrected near visual acuity (UNVA), manifest refraction, central corneal thickness, and corneal higher order aberrations were analyzed before surgery and after 3, 6, and 12 months of follow-up.
