Refractive Surgery Pearls

Remember 12. Post-operative: Watch for Steroid Response.
1. Wait for stabilization of refractive error (<0.5 D Lenticule Extraction Procedures:
1. Refractive range: Myopic sphere range 0.50 -10.00
change in refraction over a period of 1 year).
2. Written Informed consent. D, Cylinder range 0-5.00 D, Spherical equivalent
Photorefractive Keratectomy (PRK): range 0.75 -10.00 D.
1. Best results: -2.00 to -6.00 D Myopia and not fit for 2. Aim for Residual bed thickness of >250 microns.
3. A single system, the VisuMax femtosecond laser
LASIK (poor residual thickness, poor biomechanics). (Carl Zeiss Meditec, Jena, Germany) is used.
2. Gentle epithelial debridement, do not Damage the 4. Unique features: All femto, flapless, single step.

4. Flap: Steep cornea >45 D aim for thicker flaps Narayana Nethralaya, Bangalore

(>140 microns).
5. Flap: Flat cornea <40 D aim for thinner flaps.
6. Mark the cornea before cutting.
7. Simple rule: CUT WET–ABLATE DRY.
8. Free Flap: Reposition and put BCL, wait for 3

months, repeat refraction then replan.
9. Button Hole: poor visual outcome due to

subsequent scarring, wait for 3 months plan surface
ablation if possible.
10. Partial flap: Reverse the microkeratome take deeper
flap (if possible), if not, place BCL, Replan.
11. Femtosecond LASIK: Thinner flap 90 microns flap,
smoother bed, better.
