The Evolution of Laser Vision Correction
For decades, traditional LASIK surgery has been incredibly successful at freeing patients from glasses and contact lenses. However, standard LASIK is based solely on your glasses prescription (your numbers for myopia, hyperopia, and astigmatism). It treats your eye as a smooth, uniform surface.
In reality, the human cornea is not perfectly smooth. Like a fingerprint, it is covered in microscopic peaks and valleys. When light hits these tiny imperfections, it scatters, causing subtle visual distortions like glare, halos, and poor night vision. Contoura Vision (Topography-Guided LASIK) is the first technology designed to eliminate these microscopic flaws.
The Contoura Advantage
By treating the unique topography of your eye, Contoura Vision delivers results that older lasers simply cannot match:
- • High-Definition Clarity: Many patients achieve better vision than they ever had with glasses.
- • Reduced Glare & Halos: Significantly improves nighttime driving and light sensitivity.
- • Enhanced Contrast: Colors appear more vibrant and textures are sharper.
- • 100% Bladeless Safety: Utilizes advanced Femtosecond laser technology.
The Surgical Protocol
Dr. Neelam Sharma executes the Contoura Vision protocol using a two-laser system, ensuring absolute precision, safety, and comfort.
1. The Topographic Mapping (The Blueprint)
Before you ever enter the surgical suite, your eye undergoes a highly advanced scan using a Topolyzer. This device captures 22,000 unique elevation points on your cornea. This massive amount of data is used to create a 3D, computer-generated "blueprint" that is entirely unique to your eye. This blueprint is directly uploaded to the surgical laser.
2. The Bladeless Femtosecond Flap
Once your eye is completely numbed with anesthetic drops, Dr. Neelam uses a highly precise Femtosecond laser to create a microscopic, protective flap on the surface of your cornea. Unlike older methods, no metal blades are ever used. The laser creates a perfect, ultra-thin flap that is gently folded back to expose the inner corneal tissue.
3. Topo-Guided Excimer Ablation
Next, the advanced Excimer laser takes over. Guided by your custom 22,000-point topographic blueprint, the laser pulses to gently reshape your cornea. It not only flattens the tissue to correct your glasses prescription, but it specifically targets and smooths out the microscopic peaks and valleys, creating a perfectly even optical surface. This step takes only seconds.
4. Rapid Healing
The protective flap is gently folded back into place. Because of the bladeless precision of the Femtosecond laser, the flap seals itself naturally within minutes—no stitches are required. Visual recovery is incredibly rapid, with most patients experiencing life-changing clarity by the very next morning.
Candidacy and Considerations
Contoura Vision is FDA-approved for patients 18 years and older with a stable prescription. However, because it relies on reshaping the cornea, your cornea must have adequate thickness and be free from diseases like Keratoconus. The only way to determine if your eyes are eligible for this premium procedure is to undergo a comprehensive biometric and topographic evaluation at Prasan Nethralaya.
