Amniotic membrane (AM) has anti-inflammation, anti-fibrotic, and regenerative effects. Sutureless cryopreserved AM transplantation, ProKera® (Bio-Tissue, Inc., Miami, FL, USA), is easily applied by ophthalmologists in the treatment of ocular surface diseases. This retrospective study included patients with ocular surface diseases who received ProKera® between January 2022 and May 2023. Six patients (9 eyes) with a mean age of 56.8 ± 20.8 years old (range 25-74) and a mean follow-up period of 7.8 ± 4.1 months (range 1-12) were included, including 2 of recurrent conjunctival tumors with limbal and corneal involvement (cases 1-2), 1 of pterygium with marked astigmatism (case 3) and 3 of Stevens-Johnson syndrome (SJS, cases 4-6). ProKera® was inserted after the lesion excision and deep keratectomy in cases 1-3, and no recurrence or corneal complication was noted. Cases 4-5 were discharged from the intensive care unit and presented with severe chronic SJS. Most ocular manifestations improved significantly after symblepharon release and ProKera® insertion, except for corneal conjunctivalization in 1 eye (case 5). Case 6 involved early ProKera® use at the bedside during acute SJS, resulting in complete resolution. We concluded that the adjunctive application of ProKera® can be effective for ocular surface reconstruction and provides options to intervene earlier for outpatients or patients unstable for invasive surgical intervention.

OBJECTIVE: The aim of this study is to assess the efficacy of Brückner\'s test as a screening tool for identifying refractive errors by a non-ophthalmologist and to assess the inter-observer variation.
METHODS: This was a quasi-experimental study conducted at a tertiary care medical college hospital. Brückner\'s test was performed by a non-ophthalmologist followed by an ophthalmologist. The results were confirmed by cycloplegic refraction.
RESULTS: The study included 75 children (31 males and 44 females) with a mean age of 13.3 ± 1.2 years. The results of Brückner\'s test by both non-ophthalmologist and ophthalmologist showed good sensitivity and specificity when compared with cycloplegic refraction. There was a good strength of agreement between the observations of non-ophthalmologist and ophthalmologist.
CONCLUSIONS: Brückner\'s test is simple, quick, reliable, and easy to administer on children of all age groups that can provide information about the presence of refractive errors by using a coaxial light source such as direct ophthalmoscope. The application of this test by training primary care providers would be of immense value in the early identification of refractive errors.
