Introduction:
Sutureless and glue-free conjunctival autograft as a treatment modality for primary pterygium is recently gaining popularity but conventional technique of suturing conjunctival autograft is still practised widely.
Aim:
To compare the outcome of sutureless and glue-free technique with sutures for limbal conjunctival autografting in management of primary pterygium.
Materials And Methods:
A prospective interventional study was carried out in 50 consecutive eyes with primary nasal pterygium requiring surgical excision. Simple excision under local anaesthesia was performed followed by closure of the bare sclera by sutureless and glue-free conjunctival autograft in 25 eyes of 25 patients (group 1) and by the conventional method of suturing conjunctival autograft using interrupted 10-0 nylon sutures in 25 eyes of 25 patients (group 2), followed by bandaging for 24 hours in both the groups. Surgical time was recorded for both the techniques. Postoperative discomfort was assessed using preformed questionnaires. The patients were followed up for 6 months. During follow up, graft related complications and recurrence if any were noted.
Results:
Mean surgical time for group 1 (23.20±1.55 minutes) was significantly less as compared to group 2 (37.76±1.89 minutes); (p=0.001). Postoperative symptoms were seen in less number of patients (20%) and were of shorter duration (2 weeks) in group 1 as compared to group 2 with 20 (80%) patients having symptoms lasting for 4 weeks; (p<0.001). Recurrence rate and conjunctival granuloma formation rate for group 1 (0%) and for group 2 (4%) were statistically insignificant.
Conclusion:
Sutureless and glue-free conjunctival autograft technique is simple, easy, safe, effective and less time consuming than sutured limbal autograft technique with less postoperative discomfort and adverse events encountered with the use of suture material. Postoperative results of both techniques are comparable. Hence sutureless and glue-free conjunctival autografting is a good technique for the treatment of primary pterygium.
