A new concept: treating corneal amblyopia with corneal wavefront guided LASIK

Article

Cases of amblyopia should undergo corneal wavefront analysis and would benefit from corneal wavefront-linked LASIK.

Cases of amblyopia should undergo corneal wavefront analysis and would benefit from corneal wavefront-linked LASIK, according to Cyres and Keiki Mehta from the Mehta International Eye Institute and Supervision Laser Center, Mumbai, India.

Over a period of one year, 60 cases of unilateral anisometropic amblyopia (age range seven to 25 years) were tested on the keratron scout topo-corneal wavefront analyser. The uncorrected and best corrected visual acuity (UCVA, BCVA) and total RMS were recorded.

LASIK was performed using a 200 Hz flying spot laser with a pupil-based tracker using a proprietary corneal wavefront-linking software (ORK-CAM; Schwind). Flaps were created using the Cariazzo-Pendular microkeratome with a 110 micron head.

Of the 60 eyes, nine improved by one line of BCVA, 47 improved by two lines and two eyes each improved by three and four lines. RMS corneal aberration decreased from between 40% to 56% and those subjects who recorded a greater reduction in RMS were also the subjects who gained more lines of BCVA.

In view of their results, the researchers concluded that all cases of amblyopia will benefit from corneal wavefront linked LASIK.
