PURPOSE
to present a patient in whom, during LASIK with the IntraLase femtosecond laser (Abbott Medical Optics), unintended epithelial (instead of anterior stromal) flaps were created in both eyes.
METHODS
a 28-year-old man underwent bilateral LASIK using the IntraLase femtosecond laser programmed to create 100-microm flaps. Flap creation was performed uneventfully in both eyes but flap thickness was thinner than attempted. The flaps were easily torn during flap lift because they appeared to consist of epithelium only. Therefore, the procedure was immediately converted to photorefractive keratectomy with the use of mitomycin C.
RESULTS
re-epithelialization occurred 3 days after the procedure in both eyes. Three months after treatment, uncorrected distance visual acuity was 20/25 in the right eye and 20/20 in the left eye with no signs of corneal haze on slit-lamp examination.
CONCLUSIONS
despite the advantages of the IntraLase femtosecond laser in the creation of a LASIK flap, complications in terms of flap thickness may occur.
目的
介绍一位患者，在双眼的 LASIK 手术中，使用 IntraLase 飞秒激光（ Abbott Medical Optics）时，意外地制作了上皮（而非前基质）瓣。
方法
一名 28 岁男性接受了双眼的 LASIK 手术，使用 IntraLase 飞秒激光编程制作 100 微米的瓣。双眼的瓣制作均顺利完成，但瓣厚度比预期的要薄。由于瓣似乎仅由上皮组成，因此在瓣掀起时很容易撕裂。因此，该手术立即改用含有丝裂霉素 C 的光性折射角膜切削术。
结果
双眼均在手术后 3 天开始重新上皮化。治疗 3 个月后，右眼的未矫正远视力为 20/25，左眼为 20/20，裂隙灯检查未见角膜混浊。
结论
尽管 IntraLase 飞秒激光在 LASIK 瓣制作方面具有优势，但可能会出现瓣厚度方面的并发症。
