Ectopia Lentis
Conditions
Brief summary
Regular follow-up is essential to successful management of congenital ectopia lentis, but it is often ignored by parents in China. With rapid economic development, there are increasing numbers of mobile phone users that allow for communication applications to be used in medical care. The investigators aimed to assess the potential of the smartphone application assisted medical service to increase patient compliance in attendance of follow-up after congenital ectopia lentis treatment.
Detailed description
Congenital ectopia lentis is a rare ophthalmic disease that seriously harms the physical and mental health of patients. Surgery is the only definite treatment at present. However, severe visual impairment is common in congenital ectopia lentis patients in China, and delayed presentation to hospital and late surgical treatment are found to be the major reasons. In China, the messaging application WeChat has become the most popular communication tool. As most congenital ectopia lentis patients' parents are younger people, they are more likely to use technology, such as WeChat, in their daily lives. In addition, it allows ophthalmologists to utilize this communication application to relay health related information and reminders to patients. This makes it feasible to apply this smartphone application in improving attendance of follow-up visits. In this trial, the investigators aimed to assess the potential of the smartphone application assisted medical service to increase patient compliance in attendance of follow-up after congenital ectopia lentis treatment.

| amblyopia therapy rate | 3 months | the rate of amblyopia therapy during 3 months after surgery |
| referral rate due to systemic diseases | 3 months | referral rate due to abnormalities in skeletal system and cardiovascular system during 3 months after surgery |
| CEL knowledge score | 3 months | change between baseline and endline scores on knowledge about CEL, including six choice questions concerning pathogenesis, symptoms and treatment of CEL |
| follow-up adherence at 1 week after surgery | 1 week | the rates of attendance at 1 week (± 2 days) after surgery |
| follow-up adherence at 1 month after surgery | 1 month | the rates of attendance at 1 month (± 1 week) after surgery |
