Purpose: The aim of this study was to compare the visual outcomes of two monofocal intraocular lenses (IOLs), with emphasis on the defocus curve.
Methods: A total of 116 consecutive eyes with cataract, undergoing phacoemulsification with IOL implantation were included in the observational case series, and divided into two groups. 71 eyes were implanted with Tecnis Eyhance and 45 with Tecnis 1 monofocal IOL. Eyes with ocular comorbidities, previous ocular surgeries and corneal astigmatism >1 Diopters (D) were excluded from the study. Complete ophthalmic evaluation including uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), uncorrected intermediate visual acuity (UIVA), corrected intermediate visual acuity (CIVA), uncorrected visual acuity (UNVA), corrected near visual acuity (CNVA) was noted and defocus levels ranging from -4.00 D to + 1.00 D were plotted postoperatively in both groups.
Results: Uncorrected intermediate visual acuity (UIVA) and uncorrected near visual acuity (UNVA) was significantly better in Tecnis Eyhance group compared to Tecnis 1 monofocal. Both the IOLs have similar performance for distance vision but visual acuity at intermediate and near is significantly better with Tecnis Eyhance compared to Tecnis 1 piece IOL.
Conclusion: Tecnis Eyhance IOL with its better defocus curve, not only provides good distance, but intermediate vision as well. With significantly better visual acuity across the range of near and intermediate vision, Tecnis Eyhance IOL can prove to be a viable and reasonable option for patients who are more dependent on intermediate vision in daily activities.

High dose aflibercept treatment in naive neovascular age-related macular degeneration.
Int Ophthalmol
January 2025
Beyoglu Eye Training and Research Hospital, University of Health Sciences, Bereketzade Camii Sk. No:2 Beyoğlu, 34421, Istanbul, Turkey.
Background: To evaluate the efficacy and safety of intravitreal injections of 4 mg (high dose) of aflibercept in treatment-naive patients with neovascular AMD(nAMD) with treat and extend(TREX) dosing regimens, and to determine the frequency of injections.
Methods: In this interventional, retrospective study a total of 15 eyes of 14 patients (eight female and 9 male) with nAMD were included. All patients were examined and OCT imaging was performed at the time of initial presentation, on the day of each injection and at subsequent follow-up visits.
Factors associated with the time of glaucoma-related adverse events onset after pediatric cataract surgery and the preferred anti-glaucomatous surgical selection.
Int Ophthalmol
January 2025
Department of Ophthalmology and Visual Science, Eye and ENT Hospital, Shanghai Medical College, Fudan University, 83 Fenyang Road, Shanghai, 200031, China.
Purpose: To describe the clinical characteristics of glaucoma-related adverse events (GRAE) after pediatric cataract surgery. More importantly, to identify the factors associated with the time of GRAE onset and the preferred anti-glaucomatous surgical procedure for this disease.
Methods: Hospitalized medical records of patients who developed GRAE, which include glaucoma and glaucoma suspect, after pediatric cataract surgery (surgical age ≤ 14 years) between 1994 and 2021 were retrospectively reviewed.
Neovascular age-related macular degeneration on three nationwide survey and register data in Finland during 2000-2017.

Department of Ophthalmology, Faculty of Medicine and Health Technology, Tampere University, Tampere, Finland.
Purpose: To evaluate time trends in the incidence and prevalence of neovascular age-related macular degeneration (nAMD) and its treatments, associated factors, and effects on vision in Finland during 2000-2017.
Methods: We used three nationwide health examination surveys representing the Finnish population aged 30 years or older. All three surveys were linked to the national care register covering nAMD diagnoses and intravitreal injections between 2000 and 2017.
