方法：选取在我院行内、外斜视手术的患者，随机分为两组，其中32例41眼(对照组)球结膜切口使用10-0缝线缝合，30例38眼(观察组)球结膜切口使用8-0可吸收缝线缝合，均采用间断、线结埋藏式缝合，对两组术后1，2wk； 1mo的切口愈合情况、患者自觉刺激症状进行观察比较。

结果：术后1，2wk观察组切口发生缝线吸收、切口豁开的眼数分别是7眼、15眼，总的发生率为39%，对照组无1眼发生缝线吸收、切口豁开现象，发生率为0，二者之间比较差异具有统计学意义(P<0.05)； 术后1mo观察组患者有33眼切口仍有缝线残留，患者眼部充血、异物感等不适建议拆线，拆线率87%； 对照组在术后2wk时切口愈合良好，41眼全部拆线，拆线率100%，二者拆线率比较差异无统计学意义(P>0.05)； 术后切口愈合时间比较，观察组切口平均愈合时间为22.30±5.45d，对照组切口平均愈合时间为15.50±1.76d，两组比较差异有统计学意义(P<0.05)； 术后1，2wk两组眼部舒适度评分比较无明显差异(P>0.05)，术后1mo对照组眼部舒适度评分(2.57±0.50)高于观察组(1.813±0.64)，差异有统计学意义(P<0.05)。

结论：显微斜视术后球结膜切口采用8-0可吸收缝线患者舒适度与10-0缝线比较并没有优势，由于缝线的过早吸收，反而出现切口的延迟愈合，建议显微斜视术后仍采用10-0缝线缝合球结膜。

METHODS:The patients undergone esotropia or exotropia surgery in our hospital were selected and randomly divided into two groups: conjunctival incision of 32 patients(41 eyes)was sutured using 10-0 nylon in control group and that of 30 patients(38 eyes)used 8-0 absorbable suture in observation group. All patients of two group were sutured using intermittently, knot buried method. Wound healing, patients perceived irritation were observed and compared at postoperative 1, 2wk and 1mo.

RESULTS: Postoperative 1 and 2wk, the number of suture absorption and incision gaping were 7 and 15 eyes in observation group, with total incidence rate of 39%, while there was no suture absorption and incision gaping occurred in control group, the incidence was 0, the difference was statistically significant between the two groups(P<0.05). One month after operation, 33 eyes' incision in observation group had some discomforts such as stitches residue, hyperemia, foreign body sensation, who were proposal to remove stitches, the stitches rate was 87%. Incision healed well after 2wk in the control group, all 41 eyes were stitched and stitches rate was 100%. There was no statistically significant difference(P>0.05). Comparing the mean postoperative wound healing time, it was 22.30±5.45d in observation group and 15.50±1.76d in control group, the difference was statistically significant(P<0.05). There was no significant difference on ocular comfort score between the two groups after 1, 2wk(P>0.05). Postoperative 1mo, ocular comfort scores in control group(2.57±0.50)was higher than that in observation group(1.813±0.64), the difference was statistically significant(P<0.05).

CONCLUSION: There was no difference using 10-0 nylon suture or 8-0 absorbable suture to suture conjunctival incision in microscopy strabismus surgery. Due to premature absorption of sutures, the incision healed delayed. 10-0 suture is recommend to suture bulbar conjunctiva in microscopy strabismus surgery.
