Clinic observation of laser in situ keratomileusis for treatment of presbyopia with hypermetropia



Clinic observation of laser in situ keratomileusis for treatment of presbyopia with hypermetropia



Chinese Journal of Ophthalmology 44(12): 1093-1097



To investigate the effects of Laser in situ keratomileusis (LASIK) for treatment of presbyopia with hypermetropia. 32 presbyopia patients (64 eyes) with hypermetropia were treated by LASIK and follow-up 1 year. The preoperative sphere was +0.75 to +3.00 D and cylinder was 0.00 to +1.75 D. For distance vision correction, the target refraction was 0.00 to -0.50 D in the dominant eye. And for near vision, the target refraction was -1.50 to -2.50 D in the non-dominant eye. The measurement including refraction, uncorrected visual acuity (UCVA), near vision, Q factor of cornea and contrast sensitivity were recorded. At 1 year after surgery a total of 53.1% (17/32) of all patients had binocular distance UCVA of 20/25 or better along with J3 or better near, and along with J4 or better near was 87.5% (28/32). The postoperative corneal refractive power was significant higher than preoperative [3 mm: (44.12 +/- 1.38) D, 5 mm: (43.42 +/- 1.53) D] and Q factor became more negative. At 1 year 87.5% (28/32) and 100.0% (32/32) of the dominant eyes treated for distance had a manifest refractive spherical equivalent within +/- 0.50 and +/- 1.00 D of intended correction, respectively; of the non-dominant eyes treated for near, 56.2% (18/32) and 90.6% (29/32) had a manifest refractive spherical equivalent within +/- 0.50 and +/- 1.00 D of intended correction respectively. The difference of sensitivity was no statistically significant between preoperative and 6 months after surgery. There were 15.6% of the eyes had dry eye syndrome and 84.4% of the patients were satisfied with LASIK at 1 year after surgery. LASIK was a effect surgery for treatment of presbyopia with hypermetropia.
