Abstract Details


to evaluate topography guided ablation profile for the treatment of simple , compound and mixed astigmatism


Dar El Oyoun Specialized Eye Hospitals, Egypt


40 eyes with astigmatism ranging from 1.5-4.5D , with or without spherical errors ranging fromn +2 to -6D where enrolled. All underwent Femto assisted Lasik using the Wavelight FS200 femtolaser and the Alcon Wavelight EX500 Excimer laser. All eyes were treated using the T-CAT topography based algorithms. All had a preoperative workup that included scheimpflug imaging ,topography ,Q value recording ,BCVA and UCVA. All intended postoperative Qvalues was aimed at -0.40. All eyes had the same evaluation 6 weeks postoperatively.


All eyes were within +/_ 0.5 Diopters SE. All had good postoperative topographies with a mean Q value of -0.22. All eyes had an UCVA of 1.0.


Topography based algorithms are accurate and effective in the treatment of naturally occuring 'virgin'astigmatism and should not be only preserved for irregular corneas or those with previous complicated corneal surgeries.
