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.
ABSTRACT
?AlM: To discuss the artificial tears on the tear film of diabetic patients with dry eye preoperatively, and the influence on the tear film’s fuctional after phacoemulsification. ?METHODS: Fifty-four diabetic patients with dry eye (60 eyes) were followed up before phacoemulsification. Preoperatively, group A ( 30 eyes in 28 cases ) was treated with Hydroxyl lndican eye drops and group B (30 eyes in 26 cases) was not treated. Postoperatively, both group A and B were treated with Tobramycin Dexamethasone eye drops, Oprah Winfrey lbuprofen eye drops and Hydroxyl lndican eye drops. Dry eye symptoms, break up time (BUT), SchirmerItest (SIt), fluorescein stain test ( Fl ) were measured at 3d preoperatively, and 1, 7, 30, 90d postoperatively. ? RESULTS: At 3d preoperatively, there was no statistical differences between the two groups for dry eye symptoms, BUT, S I t, Fl ( P>0. 05 ). At 1 and 7d postoperatively, there were significant statistical differents between the two groups for dry eye symptoms (P0. 05). ? CONCLUSlON: Using artificial tears before phacoemulsification can improve symptoms of the diabetic patients with dry eye and accelerate the recovery of the tear film.
