SIR, Pterygium surgery is typically performed in an outpatient setting with subconjunctival anesthesia.1 Owing to the short duration of action of local anesthesia, patients may experience
considerable pain and discomfort following surgery once anesthesia has worn off. Wishaw _et al_2 showed that clinically significant postoperative pain (conjunctival and corneal origin) is
reportedly experienced in 60% of patients undergoing pterygium surgery. The purpose of this prospective randomized study was to compare the postoperative pain, and symptoms of photophobia,
epiphora, and foreign body sensation, with overnight patching _vs_ placement of a bandage lens for the management of postoperative pain following pterygium surgery. RESULTS Of 30 eyes in
each group, 15/30 in the patching group and 17/30 in the bandage lens group were male. All but one case in each group had nasal pterygia. The mean age of patients was 50.1±10.6 years in the
patching group and 49.0±16.9 years in the bandage lens group. No statistically significant differences existed between the two groups with respect to age, laterality, pterygium location,
gender, size of pterygium, size of conjunctival autograft required, or preoperative visual acuity (Table 1). COMMENT Figure 1 summarizes the results of the primary and secondary end points
of the study. There was no statistically significant difference in VAS pain score or amount of pain medication taken between groups during the first week. Significantly more eyes were
reported to be photophobic on POD 0 in the bandage lens group (_P_=0.01; odds ratio=4.0). Using linear logistic regression analysis, VAS pain score predicted the amount of pain medication
taken on the same day (_P_<0.0001; no significant difference between groups). On POD 0 only, VAS pain score was statistically significantly related to the graft area required (_P_=0.023).
Age was noted to be inversely correlated to the amount of pain medication taken; for every additional year of age, a given patient would have taken 0.13 less tablets (_P_=0.0009). None of
the clinical symptoms (photophobia, epiphora, and foreign body sensation) were predicted by any of the baseline characteristic of the groups. Interestingly, postoperative pain and
requirement for pain medication (acetaminophen with codeine tablets) was similar after POD 1, when the patch was removed. The bandage lens during the first postoperative week did not appear
to improve comfort. These results suggest that both modalities help in reducing the postoperative pain following pterygium excision, although overnight patching may provide further relief
from the symptoms of photophobia. Either overnight patching or the placement of a bandage contact lens is safe and effective in the management of postoperative pain following excision of
primary pterygia with CAU. In cases where overnight patching would interfere with the visual needs of the patient, the placement of a bandage lens is preferable. REFERENCES * Smith RB,
