Conclusions 1. Both LASIK and LASEK can cause dry eye symptom, decrease corneal sensitivity, breakdown tear-film stability, damage oculo-surface tissue, but can revive gradually.
结论1.LASIK和LASEK术后均可引起不同程度的干眼不适症状、角膜知觉减退、泪膜稳定性下降、眼表组织损害,但随术后时间延长可有不同程度的恢复。

目的观察颞侧透明角膜切口的超声乳化白内障手术对角膜知觉的影响。
Objective To observe the effect of phacoemulsification with transparent temporal corneal incision on corneal sensation.
PR K术后角膜知觉在术后6个月才能恢复，LASIK术后角膜知觉约在术后1个月即恢复。
Corneal sensitivity returned to the baseline levels at 6 months after PRK and 1 month after LASIK.
结论：LASIK术后早期可导致泪膜稳定性下降，泪液分泌减少，产生干眼症状，主要原因可能与术后角膜知觉减退有关。
Conclusion: LASIK caused a decrease in tear film stability and tear secretion early stage after operation, probably due to decreased corneal sensation after LASIK.
