ABSTRACT
@#AIM: To analyze the influence of bandage contact lens on corneal refractive status and postoperative complications in patients with pterygium. <p>METHODS: Totally 116 patients with pterygium treated in the hospital between January 2018 and December 2019 were recruited in the study. They were divided into control group and observation group by random number table method, 58 cases in each group. The control group received extended pterygium resection and autologous corneal limbal stem cell transplantation. On this basis, the observation group was treated with bandage contact lens. The best corrected visual acuity(BCVA), surface asymmetry index(SAI)of corneal topography, surface regularity index(SRI), corneal refractive power and postoperative complications in the two groups were compared. <p>RESULTS: Compared with preoperation, the BCVA of the two groups was significantly higher 1mo and 3mo after operation(<i>P</i><0.05), without statistically significant difference between the groups(<i>P</i>>0.05). Corneal horizontal and vertical curvature of the two groups were significantly higher, while corneal astigmatism was significantly lower at 1mo and 3mo after surgery. Meanwhile, the observation group had significantly lower corneal astigmatism than the control group(<i>P</i><0.05). SAI and SRI of the two groups significantly decreased, which were significantly lower in the observation group than in the control group(<i>P</i><0.05). No complications such as infection, poor healing of grafts and subconjunctival cysts were observed. The incidence of eye irritation was significantly lower in the observation group than in the control group, and lower at 2wk than at 1wk before operation(<i>P</i><0.05).<p>CONCLUSION: Extended pterygium resection combined with autologous corneal limbal stem cell transplantation and bandage contact lens is more conductive to the improvement of corneal refraction in patients with pterygium, which also can reduce the incidence of eye irritation.
ABSTRACT
· AlM:To compare the therapeutic effects of different surgical methods in treating pterygium patients and to observe tear film stability. · METHODS: A total of 120 pterygium patients ( 120 eyes) were divided into three groups, each 40 cases (40 eyes).Data including SchirmerⅠtest (SⅠt), tear break-up time ( BUT) , corneal fluorescein staining ( CFS) were recorded preoperatively and postoperatively to evaluate the clinical efficacy of surgery and the effects of tear function changes. ·RESULTS:There were no significant differences in BUT in group A before the operation and one month after operation.Groups B and C showed significant difference before and after operation, but differences were not statistically significant ( all P compared it between groups B and C, there showed no significant difference; Group A showed no significant difference in SⅠt compared with preoperative, SⅠt of groups B and C were significant differences compared with preoperative (P ·CONCLUSlON: Pterygium excision combined with self-corneal limbal stem cell transplantation and Tenon capsule closed is an ideal surgical to reduce the recurrence and improve tear film function to some extent.
