PURPOSE: To report the development of an opaque bubble layer (OBL) during small incision lenticule extraction (SMILE) and analyze its potential risk factors and the clinical outcome. METHODS: A retrospective review of medical records was performed. The patients were divided into two groups in terms of OBL area following a posterior lenticule cut: OBL less than 5% of cornea and OBL greater than 5% of cornea. Preoperative parameters and clinical outcomes were compared...

PURPOSE: To compare the long-term visual outcomes of intravitreal bevacizumab (IVB) with those of photodynamic therapy (PDT) for myopic choroidal neovascularization over a 7-year period. METHODS: Eyes treated with IVB (17 eyes) or PDT (20 eyes) that were followed up for at least 7 years were included in this retrospective study. Myopic maculopathy was classified according to the international photographic classification before treatment.

BACKGROUND: Choroidal neovascularisation (CNV) is a common complication of pathological myopia. Once developed, most eyes with myopic CNV (mCNV) experience a progression to macular atrophy, which leads to irreversible vision loss. Anti-vascular endothelial growth factor (anti-VEGF) therapy is used to treat diseases characterised by neovascularisation and is increasingly used to treat mCNV. OBJECTIVES: To assess the effects of anti-vascular endothelial growth factor (anti-VEGF) therapy for choroidal neovascularisation (CNV), compared with other treatments, sham treatment or no treatment, in people with pathological myopia...

BACKGROUND: Refractive status is crucial to visual function and can change throughout life. For patients with congenital cataract, the developmental profile of refraction is complicated owing to the potential influence of diverse clinical manifestations and various treatments, and has not yet been fully characterised. METHODS: In this prospective cohort study, we enrolled patients with congenital cataract from the Childhood Cataract Program of the Chinese Ministry of Health (CCPMOH)...

BACKGROUND: The prevalence of myopia has markedly increased within the past three decades, in particular in China. Because of myopic retinopathy and myopia-associated glaucoma, myopia has become one of the leading blinding disorders. METHODS: Conducting population-based studies and school-based investigations, we assessed prevalence and incidence of myopia and associated factors in children, university students, and adults in urban and rural regions of different Chinese provinces...

The new type implantable Collamer lens with a central hole (V4c-ICL) is widely used to treat myopia. However, halos occur in some patients after surgery. The aim is to evaluate the effect of V4c-ICL implantation on vision-related daily activities. This retrospective study included 42 patients. Uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), intraocular pressure (IOP), endothelial cell density (ECD), and vault were recorded and vision-related daily activities were evaluated at 3 months after operation...

OBJECTIVE: To analyze the outcomes of photorefractive keratectomy (PRK) on residual myopia and hyperopia post-laser in situ keratomileusis (LASIK) and to compare these results with PRK on eyes without previous laser refractive surgery. DESIGN: Retrospective comparative cohort study. PARTICIPANTS: Patients undergoing PRK between 2006 and 2010 were reviewed. METHODS: Patients were divided into 4 groups, myopic or hyperopic PRK post-LASIK (mPRK-PL and hPRK-PL, respectively) and myopic or hyperopic PRK on corneas without previous laser refractive surgery (mPRK and hPRK, respectively)...

Background: The aim of this clinical trial was to check the results of laser built-in settings 3 years after ReLEx SMILE for moderate and high myopia in unselected "real life" patients. Patients and Methods: 50 myopic eyes of 27 patients were called in for examination after 3 years. 25 of these eyes with a preoperative myopia under - 6D comprised the "moderate myopia subgroup".
