Application effect of thermoelectric-coagulation combined with autologous blood coagulation in situ and postoperative corneal bandage lens wearing in autologous conjunctival flap transplantation for primary pterygium
ObjectiveTo observe the clinical application effect in autologous conjunctival flap transplantation for primary pterygium by thermoelectric-coagulation incision combined with autologous blood coagulation in situ fixing transplantation conjunctival flap and wearing corneal bandage lens after operation. MethodsFifty patients (52 eyes) with primary nasal pterygium were selected and randomly divided into experiment group, with 24 cases (26 eyes),or control group, with 26 cases (26 eyes). Pterygium resection combined with autologous conjunctival flap transplantation were performed in both groups. The experiment group received thermoelectric-coagulation incision combined with autologous blood coagulation in situ to fix transplantation conjunctival flap, and wearing corneal bandage lens after operation, while the 10-0 nylon suture fixing transplantation conjunctival flap was employed to the control group. All patients were conducted with six-month follow-up after operation. The operation duration, postoperative symptoms, complications and recurrence rate were recorded and compared between the two groups. ResultsThe operation duration of the experiment group was significantly shorter than that of the control group (P<0.05). On the 1st, 3rd and 7th day after operation, the visual analogue scale(VAS) score of the experiment group was lower than that of the control group (P<0.05), whereas there was no statistically significant difference in the VAS score between the two groups 14 days after operation (P>0.05). On the 1st, 3rd , 7th and 14th day after operation, the foreign body sensation score of the experiment group was significantly lower than that of the control group (P<0.05). There was no statistically significant difference in the incidence of individual complication or total complications between the two groups (P>0.05).One recurrence case was observed respectively in both groups within six-month follow-up, with no statistically significant difference in recurrence rate between the two groups (P>0.05). ConclusionDuring pterygium resection combined with autologous conjunctival flap transplantation, thermoelectric-coagulation incision combined with autogenous blood coagulation in situ employed to fix transplantation conjunctival flap and to wear corneal bandage lens after operation can shorten the operation duration, improve obviously the postoperative irritation symptoms of patients, and avoid the application of suture, so as to avoid re-bleeding and re-pain during suture removal, and thus shorten the treatment time.
