Objective: To evaluate the effectiveness, predictability and safety of LASIK retreatment for corecting residual myopia. Method: Forty eyes(32 patients) underwent secondary LASIK at 3~24 months after primary LASIK procedure. Following-up were three days, 1,3 and 6 months after LASIK retreatment respectively. Results: After reoperation, mean uncorrected visual acuity(UCVA) improved significantly(P<0.01), whereas best-corrected visual acuity(BCVA) had no significant difference. The mean postretreatment refraction decreased significantly than before (P<0.01). There was increased stability of refraction with the ablation diameter used (odds ratio=2.685). Conclusions: Secondary LASIK was an effective, safe method to treat regression after primary LASIK for high myopia.

They were divided into 2 groups according to preoperative diopters (-6 25- -10 00 D in 194 eyes; -10 25 -15 00 D in 214 eyes). The mean follow up was 12 months, and the results of the postoperative visual acuity, refractive diopter, corneal thickness and the diameter of the ablation zone were statistically analyzed.

The regressive operative eyes: There were 21 eyes (10 8%, post operative diopter ≥-1 00D), the mean preoperative corneal thickness was (547 7±37 0) μm ( P >0 05 in comparison with that of the normal operative eyes), the mean intra operative laser ablation diameter was (4 64±0 41) mm ( P <0 01 in comparison with that of the normal operative eyes), and the mean post operative diopter was (-1 33±0 58)D. (2) B group: There were 136 normal operative eyes (63 5%), the mean pre operative corneal thickness was (560 9±30 9) μm, the mean intra operative laser ablation diameter was (4 51±0 28) mm, and the post operative diopter was +0 50 -0 75 D. The regressive operative eyes: There were 78 eyes (36 5%), the mean pre operative corneal thickness was (538 0±31 0) μm ( P <0 01 in comparison with that of the normal operative eyes), the mean intra operative laser ablation diameter was (4 22±0 34) mm ( P <0 01 in comparison with ? that ? of ? the ? normal ? operative ? eyes), ? and ? the ? mean ? post operative ? diopter ? was ? (-1 99±1 01) D. Conclusions In cases with small laser ablation diameter and the thin pre operative corneal thickness of high myopia, after the surgery refractive regression is easy to occur.
