Résumé
Objective To compare the vision and visual quality after implantation of refractive rotationally asymmetric mutifocal IOL (SBL-3) and diffractive mutifocal IOL (Zeiss809) in cataract surgery.Methods Totally 80 patients (100 eyes) who underwent cataract surgery in our hospital from May 2016 to June 2017 were chosen in the research,followed by the implantation of SBL-3 in 39 patients (50 eyes,SBL group) and Zeiss809 in other 41 patients (50 eyes,Zeiss group).The gender,age,length of optic axis and corneal curvature between the both groups were not significantly different (all P ＞ 0.05) before surgery.Variables including far,middle and near uncorrected vision acuity,defocus curves,vision quality were observed 3 months after surgery.Objective scattering index (OSI),modulation transfer function cutoff frequency(MTFcutoff) and Strehl ratio (SR) were detected,and objective optical quality analysis system was conducted.Results Both groups has no ocular hypertension and complications after surgery.The far uncorrected vision acuity of both groups in 3 months after surgery showed significant statistic difference from preoperation (both P ＜ 0.01).There has no statistic difference between both groups in far and near uncorrected vision acuity 3 months after surgery (both P ＞0.05).SBL group showed better outcomes than that in Zeiss group in the middle uncorrected vision acuity 3 months after surgery (P =0.04).Defocus curves showed the better middle uncorrected vision acuity in SBL group than that in Zeiss group when the degree was-1.50 D (70 cm).The OSI,MTFcutoff and SR in both groups significantly improved after surgery when compared with before surgery (all P ＜0.05).And the OSI,MTFcutoff and SR 3 months after surgery had no statistic difference between the two groups (all P ＞ 0.05).Questionnaire results showed there were 3 patients in SBL group and 4 in Zeiss group complaining glare at night,and there was no statistic difference between the two groups (P ＞ 0.05).Conclusion Both refractive rotationally asymmetric mutifocal IOL and diffractive multifocal IOL shows satisfactory vision acuity after cataract surgery.Significant improvement of vision quality in both groups can be presented after IOL implantation.

AIM To investigate the clinical effects of Qingrun Yangmu Oral Liquid combined with artificial tears on dry eye visual fatigue patients due to Liver-Kidney Yin Deficiency Syndrome.METHODS Ninety patients (180 eyes) randomly and equally were divided into artificial tears group (0.1％ Sodium Hyaluronate Eye Drops),oral liquid group (Qingrun Yangmu Oral Liquid) and combination group (0.1％ Sodium Hyaluronate Eye Drops and Qingrun Yangmu Oral Liquid) underwent a ten-day course of treatment,and they had their subjective symptom score,tear secretory volume (Schirmer Ⅰ test,SIT),tear film break-up time (BUT),corneal fluorescein staining (CFS) score and visuognosis persistence observed prior to the treatment,and on the 1 lth,21st,30th days after the treatment.RESULTS All the aforementioned indices in the three groups were improved after the treatment,especially of the 11th day (P ＜0.01).Obvious changes of BUT,CFS score and visuognosis persistence at different time points,in the three groups were found as compared with those data prior to the treatment (P ＜0.05),so were the subjective symptom score and SIT in the oral liquid group and combination group (P ＜ 0.05).The combination group displayed significantly better results than the other two groups (P ＜ 0.05),which exhibited no obvious differences between the interventions of artificial tears and oral liquid (P ＞ 0.05).A markedly higher total efficacy rate of combination group than the other two groups was achieved as well (P ＜ 0.05).CONCLUSION For patients of dry eye visual fatigue due to Liver-Kidney Yin Deficiency Syndrome,Qingrun Yangmu Oral Liquid combined with artificial tears can relieve their symptoms in terms of tear secretory promotion and prolonged BUT.
Résumé
Blood-eye barrier (BEB) is one of the most important structures of organism to maintain homeostasis of the eye. However, it is the major constraint for the medication of intraocular diseases. Traditional Chinese medicines have distinctive advantages for the treatment of intraocular diseases, which can be used to regulate the physiological function of human body with low toxicity. In this article, we have briefly summarized the feature of BEB, with the domestic and foreign literatures combined, and mainly reviewed current progress in the field of study on the permeability of traditional Chinese medicines and effective components in BEB and promoting methods.
