LASIK Evaluation & Refractive Vision Correction
Safe, Science-Backed Laser Vision Correction Guidance
Laser vision correction procedures—including Bladeless Femto-LASIK, PRK (Photorefractive Keratectomy), SMILE, and Phakic ICL implantation—have helped millions of individuals worldwide reduce or eliminate their daily dependence on spectacles and contact lenses. However, the cornerstone of achieving safe, durable, and distortion-free vision is an exhaustive pre-operative clinical evaluation.
At My Vision Eye Clinic on Sarjapur Main Road, Dr. Rinku Das (MBBS, MS Ophthalmology, FIAS, FIG) conducts detailed pre-refractive assessments for residents of Kaikondrahalli, Bellandur, Haralur, Kasavanahalli, and surrounding IT corridors. Our clinical philosophy places patient safety first: we rigorously assess your corneal biomechanics, tear film stability, and peripheral retina to ensure you are truly an optimal candidate before recommending any refractive procedure.
The 6-Step Pre-LASIK Safety Evaluation
Not every eye is suitable for standard LASIK. Before determining your candidacy, Dr. Rinku Das performs a multi-step clinical workup:
01. Corneal Pachymetry
Measuring corneal stromal thickness to guarantee that adequate residual stromal bed (RSB) remains after laser reshaping, preventing post-LASIK corneal ectasia.
02. Corneal Topography & Tomography
Three-dimensional mapping of anterior and posterior corneal elevation to rule out subtle, subclinical keratoconus or irregular astigmatism.
03. Cycloplegic Refraction
Using specialized eye drops to temporarily relax the eye's ciliary focusing muscles, uncovering any latent hyperopia or pseudo-myopia.
04. Tear Film & Ocular Surface Health
Assessing tear break-up time (TBUT) and meibomian gland function. Pre-existing severe dry eye must be treated and stabilized prior to refractive surgery.
05. Dilated Peripheral Retina Screening
Myopic individuals frequently harbor asymptomatic peripheral retinal thinning, lattice degeneration, or micro-tears. If identified, these are secured with prophylactic laser barrage before undergoing refractive surgery.
06. Pupil Size Evaluation (Pupillometry)
Measuring scotopic (dark) pupil diameter to tailor the optical treatment zone and minimize night-time glare or halos.
Understanding Your Refractive Options
| Procedure | How It Works | Best Suited For |
|---|---|---|
| Femto-LASIK (Bladeless) | A femtosecond laser creates a precise, microscopic corneal flap. An excimer laser then reshapes the underlying corneal bed, after which the flap is repositioned. | Moderate myopia, hyperopia, and astigmatism with healthy corneal thickness. Rapid visual recovery within 24 to 48 hours. |
| PRK / Surface Ablation | No flap is created. The superficial corneal epithelial layer is gently removed, and the excimer laser sculpts the surface. A soft bandage contact lens protects the eye during epithelial regrowth. | Patients with thinner corneas, athletes, martial artists, or defense personnel where a flap displacement risk must be avoided. |
| SMILE (Small Incision) | A femtosecond laser carves a tiny refractive lenticule within the intact corneal stroma, which is removed through a 2 to 3 mm micro-tunnel without creating a large flap. | Moderate to high myopia with astigmatism. Offers minimal disruption to superficial corneal nerve fibers. |
| Phakic ICL (Collamer Lens) | No corneal tissue is removed. A biocompatible, foldable intraocular lens is implanted behind the iris and in front of the natural crystalline lens. | Very high myopia (-8.0 D to -18.0 D) or corneas too thin for laser ablation. Reversible procedure preserving natural corneal architecture. |
Are You Eligible for Laser Vision Correction?
- Age Requirement: You must be 18 years of age or older.
- Refractive Stability: Your spectacle prescription should have remained stable (change < 0.50 D) for at least 12 months.
- Healthy Ocular Surface: Absence of advanced keratoconus, severe dry eyes, active uveitis, or glaucoma.
- Normal Systemic Health: Absence of uncontrolled autoimmune connective tissue disorders or severe uncontrolled diabetes.
- Not Pregnant or Nursing: Hormonal fluctuations during pregnancy and breastfeeding alter corneal curvature and hydration, requiring evaluation to be deferred until several months post-weaning.
- Contact Lens Discontinuation: Soft contact lenses must be removed at least 3 to 5 days (or rigid gas permeable lenses 2 to 3 weeks) before your pre-LASIK topography to allow the cornea to resume its natural shape.
