Visual Acuity & Refractive Converter
Convert Snellen metric (6/6), Snellen Imperial (20/20), LogMAR, Decimal, and approximate dioptric refractive blur equivalent.
Evidence-Based Eye Care Tools
Clinical Eye & Vision Calculators
Clinically calibrated calculation tools developed by fellowship-trained ophthalmologists at Dr. Anil Kumar's Eye Hospital to evaluate refractive status, cataract implant power, glaucoma pressure targets, dry eye, and paediatric vision development.
45+ Years Clinical Heritage
AAPOS, ETDRS & TFOS DEWS II Standards
Supervised by Senior Consultant Surgeons
Glaucoma Target IOP & Pachymetry (CCT) Adjuster
Adjust measured intraocular pressure for central corneal thickness (pachymetry) and calculate individualized target IOP to prevent glaucoma progression.
Cataract Intraocular Lens (IOL) Power Estimator
Estimate implant lens power based on axial eye length, corneal curvature (K1, K2), and lens A-constant for clear post-operative spectacle independence.
LASIK & Refractive Surgery Suitability Index
Determine candidacy for Custom Blade-Free LASIK, PRK, or Implantable Collamer Lens (ICL) based on corneal thickness, myopia power, and tissue margins.
Diabetic Retinopathy Risk & Screening Calculator
Assess retinal microvascular complication risk based on diabetes duration, HbA1c control, blood pressure, and visual symptoms to determine dilated fundus screening intervals.
Dry Eye Ocular Surface Disease Index (OSDI)
Evaluate eye dryness, stinging, grittiness, sensitivity to light, and visual blur during reading or screen use using the validated 12-item OSDI 100-point scale.
Computer Vision Syndrome (CVS) & Digital Eye Strain Score
Quantify digital asthenopia, headache frequency, ocular fatigue, and accommodation lag from smartphone and computer monitor usage.
Pediatric Amblyopia & Strabismus (Squint) Risk Checker
Screen children for amblyopia (lazy eye), eye misalignment (strabismus/squint), unequal refractive power, and white pupil red flags.
