Abstract: Objective To explore and analysis the impact of corneal contact lenses on visual quality after pterygium resection surgery. Methods From September 2019 to December 2022, 88 cases of patients with pterygium who underwent diagnosis and treatment at Qishan County Hospital of Traditional Chinese Medicine were selected as the research subjects. Accorded to a 1:1 random number table method, the 88 patients were divided into the corneal contact lens group of 44 cases and the control group of 44 cases. Both groups were treated with pterygium excision surgery, the control group were received routine postoperative treatment, and the contact lens group were treated with wearing contact lenses to observe and record the changes in visual quality of the patients. Results At 4 weeks after surgery, the optimal naked eye vision of the two groups were significantly higher than that of the first day before surgery (P<0.05), and the optimal naked eye vision of the contact lens group at 4 weeks after surgery were also significantly higher than that of the control group (P<0.05). The incidence rates of complications such as corneal edema, subconjunctival bleeding, delayed bleeding, and high intraocular pressure at 4 weeks after surgery in the contact lens group were 4.55%, compared to 20.45% in the control group. Compared to the incidence rates of complications in the control group, that in the ontact lens group were significantly lower (P<0.05). At 4 weeks after surgery, the corneal astigmatism values of the two groups were lower than those on the 1st day before surgery (P<0.05), and compared to the corneal astigmatism values of the control group, those of the contact lens group were also significantly lower (P<0.05). At 4 weeks after surgery, the eye symptom scores of the two groups were significantly lower than those on the 1st day before surgery (P<0.05), and compared to the eye symptom scores of the control group, those of the contact lens group were also significantly lower (P<0.05). Conclusion The application of corneal contact lenses after pterygium resection surgery can improve the best naked eye vision of patients, reduce the incidence of complications,decrease the corneal astigmatism value of patients, and continuously improve their eye symptoms.
