Clinical Scorecard: Optimization of Nomograms Using VISULYZE Improves Accuracy in Astigmatism Correction for Keratorefractive Lenticule Extraction: A Retrospective Stratified Study
At a Glance
Category
Detail
Condition
Astigmatism correction in keratorefractive lenticule extraction (KLEx)
Key Mechanisms
VISULYZE software enables data-driven nomogram optimization for improved refractive accuracy.
Target Population
Patients undergoing KLEx with varying severities of astigmatism.
Care Setting
Ophthalmology surgical practice
Key Highlights
100% of VISULYZE group achieved UDVA of 20/20 or better at 3 months.
Significantly lower residual astigmatism in VISULYZE group (99% vs. 93.5%).
VISULYZE-assisted optimization showed consistent benefits across low-to-moderate and high astigmatism subgroups.
Stratified analysis demonstrated improved SE accuracy with VISULYZE.
Efficacy and safety indices did not differ significantly between groups.
Guideline-Based Recommendations
Diagnosis
Assess astigmatism severity prior to KLEx.
Management
Utilize VISULYZE for nomogram optimization in KLEx.
Monitoring & Follow-up
Evaluate uncorrected and best-corrected distance visual acuity postoperatively.
Risks
Consider potential for undercorrection in astigmatism correction.
Patient & Prescribing Data
206 eyes undergoing KLEx with astigmatism.
VISULYZE improves accuracy in both spherical and astigmatic correction.
Clinical Best Practices
Incorporate data-driven nomogram adjustments in surgical planning.
Stratify patients by astigmatism severity for tailored treatment.
