Microelectromechanical system‐based devices for the diagnosis, treatment, and monitoring of ophthalmic diseases

Interdisciplinary Medicine, Volume 4, Issue 3, May 2026.
Due to the characteristics of miniaturization, high sensing performance, integration, and high comfort, MEMS‐based devices were employed to design sensors, imaging systems, drug delivery systems, retinal prosthesis, surgical tools, and wearable products for the ophthalmic disease diagnosis, treatment, and monitoring.

Astigmatism-type-specific impact of peripheral corneal thickness on anterior keratometric profile changes after temporal clear corneal incision cataract surgery

Scientific Reports
Postoperative astigmatism remains a concern after temporal clear corneal incision (TCCI) cataract surgery, especially in eyes with preexisting corneal astigmatism. This study investigated whether peripheral-to-central corneal thickness ratios can predict
