Evaluating the post-operative effect of transepithelial corneal collagen crosslinking (CXL) on corneal ectasia, a condition following laser-assisted in situ keratomileusis (LASIK).
CXL was performed on 18 eyes of 16 patients; in nine instances, this was done in conjunction with a LASIK flap lift procedure. The procedure utilized a 365 nm wavelength and a power density of 30 mW/cm².
The procedure involved either a four-minute pulse treatment or a transepithelial flap-on technique (n=9 eyes; 365 nm, 3 mW/cm^2).
Using a 30-minute strategy for completion. Twelve months after the surgical procedure, the postoperative shift in maximum keratometry (Kmax), anterior elevation, posterior elevation, spherical equivalent (SE), logMAR uncorrected distance visual acuity (UDVA), aberrations, and central corneal thickness (CCT) was determined.
A total of eighteen eyes, from sixteen patients (eleven male, five female), were included in the study's analysis. type III intermediate filament protein Compared to flap-lift CXL, Kmax flattening showed a greater extent after flap-on CXL, demonstrating statistical significance (P = 0.014). Stability in endothelial cell density and posterior elevation was observed throughout the duration of the follow-up period. At 12 months post-flap-on CXL, the indices of vertical asymmetry (IVA), keratoconus (KI), and central keratoconus (CKI) exhibited a decline, statistically significant (P < 0.05), whereas no such significant changes were observed in the flap-off CXL group. Spherical aberrations and the total root mean square values diminished after flap-lift CXL at 12 postoperative months, yielding statistically significant results (P < 0.05).
Post-LASIK keratectasia disease progression was effectively halted through the use of transepithelial collagen crosslinking in our investigation. In these cases, we recommend the flap-on surgical approach.
Our research indicated that transepithelial collagen crosslinking was successful in arresting disease progression in the post-LASIK keratectasia cases we examined. We strongly recommend using the flap-on surgical procedure in these particular situations.

To quantify the therapeutic success and tolerability of accelerated cross-linking (CXL) in pediatric cases.
An observational study of progressive keratoconus (KC) development in pediatric patients under 18 years of age. With the accelerated epithelium-off CXL protocol, sixty-four eyes from thirty-nine cases were processed. Visual acuity (VA), slit-lamp evaluation, refraction data, pentacam keratometry (K) measurements, corneal thickness, and the point of minimal pachymetry were all recorded. The cases received follow-up attention on days 1, 5, and 1.

The analysis revealed a statistically significant enhancement in the mean VA, K, and mean corneal astigmatism metrics (p < 0.00001). Accelerated CXL treatment resulted in a reduction of the Kmax reading from an initial range of 555 to 564 diopters (D), spanning from 474 to 704 D preoperatively, to a range of 544 to 551 diopters (D), covering the range of 46-683 D postoperatively, after 12 months. Two cases demonstrated progression in their development. Sterile infiltrate and persistent haze represented the encountered complications.
In pediatric KC, accelerated CXL demonstrates both effectiveness and efficacy.
Pediatric keratoconus (KC) shows marked improvement with the accelerated CXL procedure, proving its effectiveness and efficacy.

Through the application of an artificial intelligence (AI) model, this study sought to determine and evaluate clinical and ocular surface risk factors associated with keratoconus (KC) progression.
Four hundred and fifty keratoconus (KC) patients participated in the prospective study. The classification of these patients utilized the random forest (RF) classifier, a model previously applied to investigate longitudinal tomographic parameters in a study that assessed both progression and non-progression. Through a questionnaire, factors impacting clinical and ocular surface risks were identified, including eye rubbing frequency, indoor time spent, lubricant and immunomodulator topical medication use, computer time, hormonal fluctuations, hand sanitizer use, immunoglobulin E (IgE) levels, and vitamin D and B12 levels from blood. An AI model was created to analyze whether these risk factors demonstrated a connection to the future course of KC advancement, compared to instances without progression. The area under the curve (AUC), and other metrics, were the focus of the evaluation.
Based on tomographic AI analysis, 322 eyes were identified as progressing, contrasting with 128 eyes that showed no progression. Of those cases displaying tomographic progression, 76% were correctly predicted to progress based solely on the initial clinical risk factors. Conversely, 67% of cases without radiographic progression were accurately anticipated to remain stable based on these same factors. Concerning information gain, IgE held the top spot, succeeded by the presence of systemic allergies, vitamin D levels, and eye rubbing. ME-344 mw The AI model's accuracy in predicting clinical risk factors was measured at an AUC of 0.812.
This research underscored the significance of utilizing AI for categorizing and characterizing patient risk based on clinical factors, potentially influencing the course of KC eye disease and enhancing treatment approaches.
AI's application in stratifying and profiling patients according to clinical risk factors, as demonstrated by this study, is crucial for understanding and managing the progression of keratoconus (KC).

The present study investigates the dynamics of follow-up and the motivations behind discontinuation of follow-up in keratoplasty patients receiving treatment at a tertiary eye care centre.
A retrospective, cross-sectional study was conducted at a single center. The study encompassed corneal transplantation procedures on 165 eyes. Visual acuity measurements pre and post-surgery, recipient demographics, keratoplasty justifications, follow-up duration, and the final graft condition were all included in the collected data regarding recipients and keratoplasty procedures. The primary focus of the study was to uncover the reasons for graft recipients' discontinuation of participation. LTFU was determined when a patient failed to keep any of the subsequent follow-up appointments, including four at two weeks, three at one month, six at one month, twelve at two months, eighteen at two months, twenty-four at three months, and thirty-six at six months post-surgery. A key secondary endpoint involved assessment of best-corrected visual acuity (BCVA) among those participants who completed the final follow-up.
Following up with recipients at 6, 12, 18, 24, and 36 months yielded response rates of 685%, 576%, 479%, 424%, and 352%, correspondingly. Age and the distance from the central location proved to be crucial determinants in cases of lost follow-up. Patients with failed grafts, requiring transplantation, and those with penetrating keratoplasty for visual purposes, were important factors in achieving complete follow-up.
A common roadblock to effective post-transplant corneal care is the difficulty in conducting follow-up. In the delivery of follow-up care, special consideration should be given to elderly patients and those in remote communities.
Post-transplant corneal care frequently faces the obstacle of inadequate follow-up. Patients who are elderly or live in remote areas deserve preferential treatment for follow-up appointments.

Clinical results of therapeutic penetrating keratoplasty (TPK) procedures in patients with Pythium insidiosum keratitis, treated with linezolid and azithromycin-based anti-Pythium therapy (APT).
A meticulous retrospective examination was undertaken on patient medical records, for the period from May 2016 to December 2019, specifically focusing on those with P. insidiosum keratitis. bionic robotic fish Patients receiving APT for a minimum of two weeks, subsequently undergoing TPK, constituted the study cohort. Data pertaining to demographic details, clinical presentations, microbial data, the surgical procedure, and subsequent postoperative results were cataloged.
Of the 238 cases of Pythium keratitis observed during the study period, 50 met the required inclusion criteria and were thus incorporated into the study. In the infiltrate, the median of the geometric mean was 56 mm, with the interquartile range falling between 40 and 72 mm. Patients' surgical procedures were preceded by a median of 35 days (interquartile range 25-56) of topical APT application. Worsening keratitis, at a rate of 82% (41 out of 50 cases), was the most frequent symptom indicative of TPK. No repeat infection was found. Of the 50 eyes examined, 49 (98%) displayed a stable anatomical globe. The survival rate of the median graft was 24 months. Following a median follow-up period of 184 months (IQR 11-26 months), 10 eyes (20%) demonstrated a noticeable graft, resulting in a median visual acuity of 20/125. A clear graft was found to be significantly associated with a graft size under 10 mm, as evidenced by statistical significance (P = 0.002) of this observation (5824, CI1292-416).
Performing TPK subsequent to the administration of APT leads to positive anatomical outcomes. Grafts smaller than 10 mm exhibited a greater likelihood of survival.
The anatomical effects of performing TPK after APT administration tend to be positive. A propensity for graft survival was observed in grafts with a dimension below 10mm.
