Capsulorhexis Lab is a free training module for continuous curvilinear capsulorhexis on iPhone and iPad, for ophthalmologists and physicians in training. Utrata forceps enter through a corneal incision. You steer the instrument from its handle, outside the eye, while the tip pivots at the wound. Grasp the flap, tear along the margin, release and regrasp near the base of the flap. The tear joins its origin only when the front actually reaches it, and a radial extension stays visible. • Six progressive exercises with targets from 4.0 to 5.0 mm • Unscored free practice • Optional trypan blue and adjustable sensitivity • Geometric feedback: diameter, circularity and centration • Works offline; progress stays on the device Interface in English. No account, no advertising and no purchases. An educational model with approximate capsule mechanics. It is not clinically calibrated, gives no patient-specific guidance and does not certify surgical skill.
