Dr.Hongwei Deng received her B.D. and M.D. in medicine from Zhengzhou University in 1995 and 1999, respectively, and got the Ph.D. from Jinan University, Guangzhou, China in 2002. She has advanced her clinical experience in pediatric ophthalmology field as an observer training for 6 months in Wilmer’s Eye Institute in John Hopkins University and Boston Children’s Hospital. Now, she is the dean of the low vision department in Shenzhen Eye Hospital, also works in the pediatric ophthalmology field from 2007 till now. She was a visiting scholar and a postdoctoral researcher for one year in Schepens Eye Research Institute in 2017. Her research interests include stereo vision and vision induced diseases.
Purpose: To evaluate the effect of using stereoscopic 3 D (S3D) technology visual training system in children with amblyopia.
Methods: 30 children, 4-16 years old, 18 with ametropic amblyopia (AMA), and 12 with anisometropic amblyopia(ANA) were recruited in this study. A binocular 3D shutter glasses technology visual training system was used for training trials. Each training time lasted 1 hour, and the number of training trials totaled 33 (mean±SD=32±8) times on average, per-person. Before and after the training trials, we measured the best- corrected visual acuity (BCVA) of each eye, range of fusion by synoptophore, as well as near and distance stereopsis acuity by Yan Shaoming random-dot test and synoptophore respectively.
Result: A significant difference was found pre- and post treatment in BCVA in both kinds of amblyopia studied. Significant improvement was also found in fusion range and stereopsis acuity. The improvement of fusion range and stereopsis recovery were higher in ANA than in AMA patients. The near stereopsis acuity recovered better than the stereo acuity in distance.
Conclusion: S3D display vision training systems are indicated for the recovery of stereoacuity in children with amblyopia.
Medical Director, Downriver Optimeyes Supervision Center-Taylor
Keynote: Refractive Cataract Surgery
Time : 10:40-11:20
Fuxiang Zhang is the Medical Director, Downriver Optimeyes Supervision Center-Taylor.
Refractive cataract surgery is the trend of future with more and more cataract patients prefer or even demand partial or complete spectacle independence after cataract surgery. This presentation reviews all the modalities approved by FDA and currently used by US cataract surgeons, including Toric implants, Limbal relaxing incision, multifocal IOLs, accommodating lens, extended depth of focus IOLs (EDOF) and femtosecond laser assisted cataract surgery (FLACS). The presentation will also demonstrate why IOL monovision should be considered as the foundation of modern refractive cataract surgery. Advantages and disadvantages of each modality will be reviewed.
