Curative effect of modified Parks incision combined with rectus linear tucking on adults with concomitant strabismus
Abstract
AIM: To explore the curative effect of modified Parks incision combined with rectus linear tucking on adults with concomitant strabismus and its influences on postoperative recovery of visual function and ocular aesthetics.METHODS: A total of 160 adults with concomitant strabismus were enrolled as the research subjects between June 2019 and June 2021. They were divided into observation group(modified Parks incision combined with rectus linear tucking, 89 cases)and control group(corneal limbal trapezoid conjunctival flap incision combined with rectus linear tucking, 71 cases)according to different surgical methods. The clinical curative effect and surgical related indexes between the two groups were compared. The changes in scores of corneal fluorescence staining, standard patient of eye dryness(SPEED), visual analogue scale(VAS)and Vancouver scar scale(VSS)before and after surgery in both groups were observed. The occurrence of complications such as poor conjunctival healing and astigmatism was statistically analyzed at 1mo after surgery.RESULTS: The total response rate of surgery in observation group was higher than that in control group, and length of surgical incision was shorter than that in control group(all P<0.05). The scores of postoperative corneal fluorescence staining and dry eye in observation group were lower than those in control group, and VAS scores at 1wk after surgery were lower than that in control group(all P<0.05). Postoperative divergent fusion range, strabismus angles of short-sighted 33cm and far-sighted 5m in observation group were greater than those in control group. Convergent fusion range was smaller than that in control group, and stereopsis of short-sighted 33cm and far-sighted 5m was lower than that in control group(all P<0.05). Postoperative break-up time in observation group was longer than that in control group, lacrimal secretion was more than that in control group, and scores of corneal surface regularity index(SRI)and VSS scores were lower than those in control group(all P<0.05). The total incidence of complications in observation group was lower than that in control group(P<0.05).CONCLUSION: The modified Parks incision combined with rectus linear tucking can not only improve surgical effect and promote the recovery of visual function and tear film function in adults with concomitant strabismus, but also relieve dry eye and postoperative pain, improve ocular aesthetics and reduce the incidence of postoperative complications.
