MUMBAI, India, June 22 -- Intellectual Property India has published a patent application (202621049270 A) filed by Dhumad Pranavkumar on April 17, 2026, for Preloaded Intraocular Lens Delivery System With Mechanical Speed Regulation.
Inventor includes Dhumad Pranavkumar.
The application for the patent was published on June 12, 2026, under issue no. 24/2026.
Abstract: The present disclosure relates to a mechanically actuated intraocular lens (IOL) delivery apparatus configured for controlled insertion of foldable intraocular lenses during ophthalmic surgical procedures. The apparatus comprises a housing containing a propulsion subsystem and a lens release and preparation subsystem configured to cooperate to deliver a preloaded intraocular lens in a regulated and predictable manner. The device includes a lens holder assembly comprising a lens holder base and a lens holder cover configured to retain a preloaded intraocular lens prior to surgical use. A twist actuator is operatively connected to a release linkage configured to simultaneously release stored energy in a flat spiral constant-force spring, disengage the lens holder cover to free the intraocular lens, and activate a lubricant reservoir to apply lubricant onto the intraocular lens prior to advancement. The spring-driven propulsion mechanism is mechanically coupled to a rotatable nut engaged with a threaded screw configured to convert rotational motion into axial translation of a plunger. The plunger advances the intraocular lens into a cartridge positioned at the distal region of the apparatus, the cartridge including a delivery nozzle configured to progressively fold the intraocular lens and guide the folded lens through a surgical incision into the capsular pouch of the eye. The apparatus further includes a lever assembly configured to frictionally engage the rotatable nut and a user-actuated push button configured to proportionally vary the friction applied to the rotatable nut, thereby regulating the rotational speed of the propulsion mechanism and controlling the delivery speed of the intraocular lens. The mechanically integrated system provides coordinated activation of spring release, lens unlocking, lubrication, propulsion, and user-adjustable speed control within a single disposable device, thereby improving precision, consistency, and safety during intraocular lens implantation procedures.
