Vision correction now extends beyond simple spectacles. Advancements in materials, manufacturing, and understanding of eye physiology have led to thinner lenses, more comfortable contact lenses, and precise surgical interventions.
High-index materials produce thinner, lighter lenses. Coatings add benefits like UV protection and glare reduction.
| Material Index | Advantages | Best Applications |
|---|---|---|
| 1.50 (Standard) | Cost-effective | Mild prescriptions |
| 1.60 (Mid-index) | Reduced thickness | Moderate prescriptions |
| 1.74 (High-index) | Ultra-thin | Strong prescriptions |
Silicone hydrogels allow more oxygen to reach the cornea, reducing dryness and enabling extended wear.
Modern LASIK uses femtosecond and excimer lasers for precise corneal reshaping. Wavefront-guided techniques and eye tracking systems improve outcomes.
IOLs correct refractive errors during cataract surgery. Multifocal, toric, and accommodating lenses offer various solutions tailored to patient needs.
