RESUMEN
@#AIM: To study the effect of preoperative meibomian gland physiotherapy on ocular surface after cataract surgery in patients with meibomian gland dysfunction(MGD). <p>METHODS: Totally 76 eyes of 76 cataract patients with MGD were selected and divided into two groups by random grouping method in our hospital. Patients in the experimental group was given eyelid hot compress and meibomian gland massage before operation(after a full set of treatment in the hospital, patients were instructed to have family hot compress and meibomian gland massage every night), and patients in the control group was not given any treatment. Cataract phacoemulsification and intraocular lens implantation were performed in both groups. The non-invasive tear break-up time(NITBUT)and the tear meniscus height(TMH)were examined by ocular keratograph, the thickness of lipid layer(LLT)were examined by LipiView, and the Ocular Surface Disease Index(OSDI)questionnaire was conducted at 1wk before operation and 1wk, 1mo after operation.<p>RESULTS: The NITBUT, TMH and OSDI were significantly different between the two groups before and after operation(<i>P</i><0.05). The NITBUT were significantly lower than in both groups 1wk and 1mo after operation than those before operation(<i>P</i><0.05). The NITBUT in the control group were significantly lower than those in the experimental group 1wk and 1mo after operation(<i>P</i><0.05). The TMH was significantly lower one week after operation in the experimental group than those before operation(<i>P</i><0.05), and returned to the preoperative level 1mo after operation(<i>P</i>>0.05). The OSDI were significantly improved after operation compared with those before surgery in both groups 1wk and 1mo(<i>P</i><0.05). The OSDI in the control group were significantly higher than those in the experimental group 1wk and 1mo after operation(<i>P</i><0.05).<p>CONCLUSION: Phacoemulsification of cataract can destroy the function of meibomian gland and the ocular surface condition in patients with meibomian gland dysfunction. However, preoperative meibomian gland physiotherapy can significantly improve the ocular surface condition of patients with meibomian gland dysfunction after cataract surgery, and improve the satisfaction of patients.
RESUMEN
Objectivc To compare the accuracy and practicability of OPD-Scan Ⅲ marker methods and slit light narrow band marker methods in phacoemulsification and Toric IOL implantation.Methods A prospective randomized controlled study was conducted in 70 eyes of 70 patients with regular astigmatism (1.00-3.00 D).All patients underwent phacoemulsification and Toric IOL implantation and were randomly divided into two groups according to preoperative marker methods:observant group,in which OPD-Scan Ⅲ marker methods were used in 35 eyes of 35 patients,and control group,with application of slit light narrow band marker methods in 35 eyes of 35 patients.The postoperative visual acuity,residual astigmatism and deviation of lens axis (LAD) were observed and compared between the two groups.Results The uncorrected visual acuity (UCVA) between preoperative data and 3 months after surgery was statistically significant [(0.11 ± 0.09) vs.(0.59 ± 0.25)] (P =0.000).The difference in the postoperative 1 day and 3 months LAD was no statistically significant (P ＞ 0.05).The astigmatism between preoperation and 3 months after treatment was significant [(1.88 ± 0.49) D vs.(0.54 ± 0.30) D] (P =0.000).There was no significant difference in LAD between the two groups neither the first day nor 3 months after operation (both P =0.621).Conclusion OPD-Scan Ⅲ marker methods and slit light narrow band marker methods are both highly accurate and practical,but the former requires less for operator and is more easily accepted by patients.
