Evaluation of long-term clinical outcomes after toric implantable collamer lens implantation.

Purpose: To evaluate the long-term (8-10 years) outcomes of toric implantable collamer lens (TICL) surgery.

Setting: Nagoya Eye Clinic, Nagoya, Aichi, Japan.

Design: Retrospective observational study.

Evaluation of CorvisST biomechanical parameters and anterior segment optical coherence tomography for diagnosing forme fruste keratoconus.

Purpose: To investigate the utility of biomechanical property measurements using a Scheimpflug-based tonometer (SBT) and/or anterior segment optical coherence tomography (AS-OCT) for diagnosing forme fruste keratoconus (FFK).

Methods: In this retrospective interventional case series, 23 eyes with FFK of 23 consecutive patients and 52 eyes of 52 healthy volunteers who visited our keratoconus outpatient clinic were enrolled. Logistic regression analysis was conducted to determine the causal relationship between FFK diagnosis and each parameter.
