[Evaluation of eye patching after cataract surgery in topical anesthesia].

BACKGROUND

Although postoperative eye patching is a common practice its background is not well known. Therefore the necessity of eye patching after cataract surgery in topical anesthesia from the medical point of view and the patients' subjective opinion was studied.

PATIENTS AND

METHODS

In this prospective and randomized study 133 patients received after cataract surgery either no covering of the eye (group1), a transparent eye shield for four hours (group 2), an eye pad for four hours (group 3) or an eye pad until the next morning (group 4). Clinical findings were noted and local symptoms, such as pain, foreign body sensation, tearing and photophobia were documented on a visual analogue scale (0 - 10). Furthermore, a questionnaire concerning the subjective opinion was handed out to the patient.

RESULTS

The clinical findings revealed no significant differences between the groups. The mean values for local pain were 0.94 +/- 1.56, for the foreign body sensation 1.41 +/- 2.02, for tearing 0.99 +/- 1.8 and for photophobia 1.05 +/- 1.99. Comparing the groups there was significantly more pain and foreign body sensation reported by the patients in group 3, who received eye patching for 4 hours. 91 % of the unpatched patients had no discomfort, whereas 53 % of the patients wearing an eye pad until the next morning considered it as unnecessary.

CONCLUSION

After cataract surgery in topical anesthesia only mild symptoms were noted. There were no significant differences between the groups in the objective clinical findings and the subjective feeling. These results indicate that after cataract surgery eye patching could be unnecessary.
