ABSTRACT
The corneal contact bandage lens has gained clinicians acceptance for their wearing comfort and definite curative effects in ocular surface protection and damage reparation.Recently,application fields of contact bandage lens are still expanding with continuous exploration and development of new materials and function.To noninfectious ocular surface diseases,bandage lens obviously alleviate irritate symptoms and accelerate tissue healing.The application of bandage lens in infectious ocular surface diseases remains controversial.The bandage lens has become a routine intervention of ocular trauma and corneal perforation.It can also improve ocular surface microenvironment after the surgery of glaucoma,cataract,pterygium,corneal transplantation and refraction.It is an adjuvant therapy for aniridia,dry eye and children ocular surface diseases.This review summarized the history,current corneal contact bandage lens in preventing and treating ocular surface diseases.
ABSTRACT
Objective To investigate long-term data of dry eye after LASIK in young myopia patients.Methods Young myopia patients were divided into treated group (group A) and control (group B),who were interviewed before surgery and on 1 year,3 years and 5 years after surgery.Their diopters,uncorrected visual acuity (UCVA),tear breakup time test,Schirmer I test and corneal fluorescent staining were taken,then dry eye was diagnosed and OSDI questionnaire were scored.Results The postoperative incidence of dry eye in group A was higher than that before surgery (35.6％) and decreased with time (51.7％,44.9％ and 40.7％,respectively),and there was no significant difference in group B at each time point (P ＞ 0.05).The preoperative incidence of dry eye was equal between two groups (P ＞ 0.05),which were much higher in group A after surgery (all P ＜ 0.05).In group A,the postoperative constituent ratio of mild dry eye was the majority and decreased with time (65.6％,52.8％,41.7％,respectively),while moderate and severe dry eye was increased,especially the latter (6.6％,11.3％ and 16.7％,respectively;P ＜ 0.05).At 5 years after surgery,the UCVA and visual function score in dry eye patients were lower than those of non-dry eye patients (all P ＜ 0.05),while the residual refraction and ocular symptom score were higher than those of dry eye patients (all P ＜ 0.05).Conclusion Dry eye disease may last for a long time and may getting worse after LASIK.Therefore,we should pay more attention to the development of dry eye long after LASIK in young myopic patients.
