Comparison between IOL MASTER 500 and MYAH with vector analysis in low and mild anterior corneal astigmatism
CONCLUSIONS: The instruments appear to be interchangeable for measurements of AL, keratometry, and magnitude of ACA with high agreement between the two devices. Also, in the presence of low astigmatism, the two instruments give the same results in terms of ACA.PMID:37919941 | DOI:10.1177/11206721231210895 (Source: European Journal of Ophthalmology)

Effect of dry eye on the reliability of keratometry for cataract surgery planning
CONCLUSION: Dry eye can affect the reliability of keratometry measurements before cataract surgery, thereby affecting the accuracy of intraocular lens power calculations. In cataract surgery planning, it is necessary to detect subjective and objective indicators of dry eye in patients and carry out effective intervention so as to avoid refractive errors caused by inaccurate keratometry measurements.PMID:37919153 | DOI:10.1016/j.jfo.2023.04.016 (Source: Journal Francais d Ophtalmologie)

Parameters of a basic ophthalmic examination that can ensure proper timing of corneal crosslinking in patients with keratoconus
ConclusionsIt is advisable to refer patients with keratoconus to a specialized facility for CXL when either of the following conditions is present: (i) UCDVA (decimal visual acuity) ≥ 0.06 or (ii) CDVA (decimal visual acuity) ≥ 0.3. (Source: International Ophthalmology)

Estimating the Genetic Contribution to Astigmatism and Myopia in the Mexican Population
This study aimed to estimate the genetic contribution to astigmatism and myopia in the Mexican population. A sample of 1399 families, including 243 twin pairs and 1156 single twins, completed a medical questionnaire about their own and their co-twin's diagnosis of astigmatism and myopia. Concordance rates for astigmatism and myopia were estimated, and heritability and genetic correlations were determined using a bivariate ACE Cholesky decomposition method, decomposed into A (additive genetic), C (shared environmental) and E (unique environmental) components. The results showed a higher concordance rate for astigmatism and ...

Trends in the prevalence of common ocular conditions and comparison of ophthalmic outpatient utilisation related to these conditions in children with and without various types of disabilities: analysis of nationwide population-based data from Taiwan, 2014-2019
Conclusions
The prevalence of common ocular conditions and the corresponding vision care required vary across types of disabilities among children. Healthcare policies must account for children at high risk of various ocular conditions, including those with less common disabilities. (Source: BMJ Open)

Eye and Orbital Anatomy in Metopic Synostosis
CONCLUSIONS: Metopic synostosis patients have more shallow, wider, and higher orbits. Eye dimensions are similar in sagittal synostosis patients, although globe height was smaller. Altered orbital and eye dimensions in metopic synostosis probably have a causal relation with an unknown order of development. How these dimensions relate to future orthoptic anomalies (eg, refractive error) needs further investigation.PMID:37823032 | PMC:PMC10564306 | DOI:10.1097/GOX.0000000000005303 (Source: Hand Surgery)

Toric Intraocular Lens versus Peripheral Corneal Relaxing Incisions for Astigmatism between 0.75 and 2.5 Diopters: 5-Years Outcomes
CONCLUSIONS: Although there was no difference between the overall visual and vision-related quality of life outcomes between tIOLs and PCRIs, an increase in refractive astigmatism and reduction in distance emmetropia with time was noted in both groups.PMID:37789513 | DOI:10.1080/02713683.2023.2260961 (Source: Current Eye Research)

Effect of femtosecond laser-assisted arcuate keratotomy versus toric intraocular lens implantation on correction of astigmatism in cataract surgery: a systematic review and meta-analysis
ConclusionsFSAK combined with non-toric IOL implantation was found to be less effective than TIOL implantation in correcting preoperative corneal astigmatism in cataract patients. The difference in the effectiveness of astigmatism correction between the two surgical methods seems to diminish, as the degree of preoperative corneal astigmatism decreases.

Refractive Surgical Correction and Treatment of Keratoconus
Keratoconus (KC) is an ectatic corneal disorder that causes, as the irregular astigmatism progress, severe vision loss. Surgical options allow us to correct, partially or totally, the induced refractive error.Intracorneal ring segments (ICRS) implantation represents a minimally invasive surgical option that improves visual acuity by modifying the corneal geometry. The success rate after ICRS implantation is high, and most importantly, the overall complication rate is low. Corneal allogenic intrastromal ring segments consists of ring segments derived from allogenic eye bank-processed donor corneas that can be combined simul...

Development of interface haze after femtosecond laser-assisted in situ keratomileusis with accelerated corneal crosslinking: a case series
ConclusionsThe development of clinically significant interface haze is a relatively rare complication after FS-LASIK Xtra but tends to have a higher incidence and intensity compared to conventional stromal surgery such as FS-LASIK. Timely treatment and close follow-up are essential to patients undertaking FS-LASIK Xtra. (Source: International Ophthalmology)
