To find out whether wavefront-guided femto-LASIK can improve the postoperative uncorrected visual acuity (UCVA) in comparison with preoperative best spectacle corrected visual acuity (BSCVA) in the group of adult refractive amblyopes.
Republican Ophthalmological Center, Minsk, Belarus.
Seventeen eyes of 10 consecutive patients (7 isometropic and 3 anisometropic refractive amblyopes without strabismus) underwent wavefront-guided LASIK procedure on WaveScan WaveFront System / STAR S4 IR eximer laser platform (AMO, Santa Clara, CA, USA). Flap creation was performed on IntraLase FS60 femtosecond laser. The efficacy was defined as the positive difference between 3 month post-op UCVA and preoperative BSCVA (both measured in decimal system), 3 month post-op BSCVA was also measured. Mean spherical equivalent refraction (MRSE) in the group was -5.17 +/- 2.42. Target refraction in all cases was emmetropic. Mean pre-op BSCVA was 0.55 +/- 0.25.
In 9 cases we observed the improvement in post-op UCVA in comparison with preoperative BSCVA, in 5 cases there were no significant difference between two values and in 2 cases weve registered the deterioration of post-op UCVA in comparison with preoperative BSCVA (caused by the undercorrection, post-op BSCVA in both cases resembled pre-op BSCVA). Three month postoperative MRSE was -0.1 +/-0.6 and mean UCVA 0.62 +/- 0.22, mean BSCVA was 0.67 +/- 0.27.
Wavefront guided femto-LASIK is a predictable and effective way of correcting myopia in adult amblyopic patients and is able to improve postoperative UCVA and BSCVA in comparison with preoperative BSCVA. NO financial disclosure.
