Abstract

PURPOSE

To report a case of apparent corneal ectasia after intrastromal femtosecond laser treatment for presbyopia (INTRACOR).

METHODS

A healthy 56-year-old male with low hyperopia underwent an unremarkable bilateral INTRACOR procedure in March/April 2011. The patient was discharged after follow-up and returned 5 years later.

RESULTS

Before discharge, the monocular logarithm of the minimal angle of resolution uncorrected distance visual acuity (UDVA) values were R, 0.0 and L, 0.10. In both eyes near (UNVA) visual acuities were 0.0. There were signs of slight posterior central corneal steepening without loss of corneal stability. Five years postop, monocular UDVA and UNVA values were 0.4 and 0.0, respectively. Ectasia was observed in both eyes, and the centrally placed 5 concentric rings after the INTRACOR procedure were visible under slit-lamp biomicroscopy.

CONCLUSIONS

There is no clear reason to explain why the patient developed bilateral corneal steepening. It could be that the patient's corneal stromal fibers gradually weakened over this 5-year period.

摘要

目的

报告一例在进行基质内飞秒激光老视治疗术（INTRACOR）后出现明显角膜扩张的病例。

方法

一名患有低度远视的56岁健康男性于2011年3月/4月接受了双侧无异常的INTRACOR手术。患者在随访后出院，5年后返回。

结果

出院前，单眼未矫正远视力（UDVA）的最小分辨角对数视力值右眼为0.0，左眼为0.10。双眼近视力（UNVA）均为0.0。有中央角膜后部轻度陡峭的迹象，但角膜稳定性未丧失。术后5年，单眼UDVA和UNVA值分别为0.4和0.0。双眼均观察到角膜扩张，在裂隙灯生物显微镜下可见INTRACOR手术后中央放置的5个同心环。
