Intelligent Lens Tilt Detection

LENSAR’s superior imaging system brilliantly collects biometric data including anterior and posterior corneal curvature radius, corneal thickness, anterior chamber depth, anterior and posterior lens curvature radius, and lens thickness from multiple angles. By collecting this data at multiple angles and in the x-, y, and z-axes, LENSAR® has the ability to detect and compensate for lens tilt, which contributes to the safety of the laser treatment by ensuring the fragmentation pattern fits within the capsular bag without encroachment on the capsule.

Lens tilt compensation contributes to free-floating and perfect capsulotomies for more consistent ELP

LENSAR’s intelligent lens tilt detection allows for the creation of free-floating capsulotomies nearly 100% of the time.1 And because LENSAR’s fluid-filled patient interface allows for precise laser delivery without distortion, free-floating capsulotomies can be achieved even for eyes with decentered or small pupils.

  • System automates capsulotomy size, shape, and location
  • Capsulotomy can adjust to within 250 µm of the pupillary margin when system detects intraoperative pupil constriction
  • Capsulotomies can be centered on the optical axis or pupil
  • Precise capsulotomies may contribute to more consistent effective lens positioning (ELP) and improved refractive outcomes2,3
