Follow-up was carried out from the date of surgery until 36 months later. Bowman layer grafts were positioned into a mid-stromal pocket performed by a femtosecond laser and patients were evaluated up to 3 years after surgery.Results: Corneal flattening of 5.49 D ( P = 0.0020) in Kmax was observed, increased in corneal pachymetry, and an improvement best-corrected visual acuity measured in logarithm of minimum angle of resolution (LogMAR) from 0.89 to 0.60 and tolerance to contact lens from 42% of the patients to 100% of them.

Our comparison group was a retrospective cohort of patients (23 eyes from 15 patients) who previously underwent DSO without the use of a postoperative rho-kinase inhibitor between September 2014 and March 2020.Results: Use of netarsudil after DSO statistically significantly reduced time to corneal clearance, improved best corrected visual acuity, reduced pachymetric thickness, and increased central endothelial cell count (ECC) at 6 months postoperatively. Importantly, central ECC continued to increase beyond 12 months after DSO with central ECC still statistically significantly greater in eyes that received netarsudil than in eyes that received no netarsudil.Conclusions: A rho-kinase inhibitor, such as netarsudil, after DSO should be used if available to achieve the best corneal clearance, best corrected visual acuity, and ECC after surgery.","PeriodicalId":10710,"journal":{"name":"Cornea","volume":" ","pages":"286-290"},"PeriodicalIF":1.9,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141081038","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The average treatment duration was 18 months. In all patients, previous treatments with antihistamines, mast cells stabilizers, topical steroids and topical cyclosporine, and systemic steroids did not result in sufficient improvement. The severity of inflammation was evaluated during clinical examinations and the patients' subjective assessment of their quality of life.Results: In all 6 patients, signs and symptoms showed significant improvement within 2 to 4 weeks of initiating systemic cyclosporine treatment. All patients were able to discontinue regular steroids use and reported a significant improvement in their quality of life.

The number increased from 2 annual procedures in the first half of the study period to 5 in the second half ( P = 0.01). Preoperative corneal perforation was present in 43.5% (n = 30) of the eyes. Two years after surgery, follow-up data were completed in the register for 53 eyes; of these, 62.3% (n = 33) were considered to have functioning grafts, and 20.8% (n = 11) had experienced a rejection episode. The visual acuity improved from hand motion to counting fingers ( P = 0.002), and the proportion of eyes with a visual acuity of ≤1.0 logMAR increased from 5.7% (n = 3) before the surgery to 45.3% (n = 24) at the 2-year follow-up ( P < 0.001).Conclusions: The number of active infectious keratitis cases undergoing keratoplasty à chaud increased in Sweden during the 21st century. Most of the cases were successful regarding the structural integrity of the bulb, that is, \"had a saved eye\" and even a functioning graft 2 years after corneal transplantation. The visual gain was distinct, albeit modest.

Patients between the period of June 2000 and September 2022 were included in this study. Parameters such as patient age, sex, ocular history, visual acuity, K2, Max-K, and thinnest corneal thickness pachymetry (TCT) were analyzed.Results: There were 4342 untreated eyes from 2171 patients with keratoconus. A total of 333 patients showed progression of either Max-K, TCT, or both, whereas 1838 patients showed stable parameters. Factors associated with a higher incidence of progression in Max-K were younger baseline age (HR 0.96 per year older; 95% CI 0.95-0.98, P < 0.0001) and a higher baseline intereye asymmetry in Max-K (HR 1.02 per higher diopter; 95% CI 1.00-1.04, P = 0.04). A younger baseline age was the only predictor of progression in TCT (HR 0.97 per year older; 95% CI 0.95-0.99, P = 0.001).Conclusions: Age is the most significant predictor of progression for both corneal thinning and progression of Max-K. Interocular asymmetry in Max-K at baseline could be used as part of an algorithm for determining the risk of keratoconus progression. It is recommended that patients with higher interocular asymmetry in Max-K have a closer follow-up of both eyes as they are at a higher risk of progression.","PeriodicalId":10710,"journal":{"name":"Cornea","volume":" ","pages":"337-341"},"PeriodicalIF":1.9,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141445845","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

After staining the surface of a conjunctival cyst with a dark-purple marker pen, an incision was made into the conjunctival cyst using a 26-gauge needle. Low-energy photoablation using 3 × 3 grids of spots was then applied around the incision site for a mean of 50 times. The laser spots were 400 μm in size, the power delivered ranged from 400 to 450 mW, and the duration of each laser pulse was 80 ms.Results: During a mean follow-up period of 6.5 months (range 6-16 months), 84 cases of conjunctival cysts (89.4%) were successfully corrected by conducting either 1 or 2 laser sessions. The cyst was completely resolved after a single laser session in 74 cases (78.7%). There were 20 cases of recurrence, which involved fixed, thick, and large cysts. The conjunctival cyst recurred again after the second laser session in 2 of the 12 eyes in which the procedure was repeated. The remaining 8 cases were observed without additional treatment. No postoperative complications such as conjunctival scarring or persistent ocular irritation were observed.Conclusions: Pattern scan laser photoablation of a conjunctival cyst with the adjunctive use of cyst surface staining to increase the amount of thermal laser energy absorption is a simple and effective method for treating conjunctival cysts in an outpatient clinic.","PeriodicalId":10710,"journal":{"name":"Cornea","volume":" ","pages":"275-281"},"PeriodicalIF":1.9,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141476139","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
