Resumen
PURPOSE: To present one-year results after LASIK in high hyperopia with spherical equivalent (SEQ) of more than 3D using WaveLight Allegretto Wave 400Hz excimer laser and WaveLight Rondo microkeratome.
METHODS: Fifty-one eyes of 30 patients underwent LASIK to correct hyperopia.
WaveLight Allegretto Wave 400 Hz excimer laser was used and flaps were created with WaveLight Rondo microkeratome. Mean preoperative SEQ was +4.16 ± 1.44 D (range: +3.25 to +8.00), and mean cylinder was -1.44 ± 1.52 D (range: 0 to -5.00). Mean preoperative UVA was 0.10 ± 0.12 (range: 0.01 to 0.40), while mean BSCVA was 0.69 ± 0.18 (range: 0.40 to 1.00). Uncorrected and best spectacle corrected visual acuities (UVA and BSCVA), as well as manifest refraction, were recorded at 1, 6 and 12 months after the treatment.
RESULTS: One month postoperatively UVA and BSCVA increased to 0.52 ± 0.23 (range:
0.3 to 0.8) and 0.66 +/- 0.19 (range 0.4 to 1.0) respectively and did not change statistically over 1-year interval (p=0.154 and p=0.196 respectively). One eye lost one line, 35 maintained, and 5 eyes gained one line of BSCVA. Manifest SEQ decreased to -0.35 ± 0.88 D (range: -2.00 to +1.00) at 1 month and stabilized at -0.16 +/- 0.65 D (range: -0.75 to +1.00) at 1-year follow-up (p<0.05). Manifest cylinder decreased to -0.41 ± 0.50 D (range:
-2.00 to 0) at 1 month and did not change statistically over 1-year (p=0.500).
CONCLUSIONS: LASIK in high hyperopia using WaveLight Allegretto Wave provided predictable and stable results over the period of 1 year follow-up, comparable to the outcomes of low to moderate hyperopia. An initial overcorrection was planned to counteract a possible regression.
