Phacoemulsification And Stitch-less Foldable Lens Implantation Surgery

Phacoemulsification with stitch-less foldable intraocular lens implantation is the most advanced and widely performed cataract surgery technique available at Moolchand Hospital, recognized among the top ophthalmology hospitals in Delhi. It represents the culmination of decades of surgical innovation — replacing the entire cloudy crystalline lens with a clear artificial intraocular lens (IOL) through a tiny self-sealing corneal incision of just 2–2.8mm, using no sutures, enabling rapid visual recovery and same-day discharge.

A cataract — the clouding of the eye's natural crystalline lens — is the leading cause of reversible blindness worldwide, developing gradually with age (senile cataract) or from diabetes, steroids, trauma, or congenital factors. The affected lens scatters light before it reaches the retina, causing progressive visual blurring, glare, halos around lights, reduced contrast sensitivity, and difficulty with reading and driving. Phacoemulsification cataract surgery completely removes the cloudy lens and replaces it with a clear artificial IOL, dramatically restoring vision typically within 24 hours.

The procedure is performed under topical anaesthesia (eye drops only — no injections, no patches) as a day-care surgery, taking approximately 15–20 minutes. A diamond blade creates a tiny 2–2.8mm clear corneal incision that is self-sealing (no sutures required at the end). The anterior capsule of the lens is opened using a circular, curvilinear capsulorhexis. Viscoelastic material protects the delicate corneal endothelium throughout the procedure.

The phacoemulsifier handpiece — delivering high-frequency ultrasound energy at 40,000 cycles per second through a titanium tip — is inserted into the eye. The nuclear material of the cataract is sculpted, cracked, and emulsified (liquefied) in situ using various nuclear disassembly techniques (stop-and-chop, phaco-chop, divide-and-conquer), then aspirated from the eye along with the softer cortical material — leaving the thin posterior capsule intact as the scaffold for IOL placement.

A carefully selected foldable IOL — a polymethylmethacrylate (PMMA), acrylic, or silicone lens folded tightly within an injector cartridge — is inserted through the same 2–2.8mm incision and unfolds within the capsular bag to its full diameter (typically 5.5–6mm optic), centered precisely in the visual axis. The self-sealing corneal incision requires no sutures, minimizes induced astigmatism, and allows same-day discharge with rapid functional vision recovery.

Advanced IOL options available at Moolchand Hospital include monofocal IOLs for distance vision (spectacles needed for reading), toric IOLs correcting pre-existing corneal astigmatism for spectacle-free distance vision, extended depth of focus (EDOF) IOLs and multifocal IOLs providing clear vision across a range of distances (distance, intermediate, and near) — potentially achieving spectacle independence across all distances, and light-adjustable lenses for post-operative fine-tuning of refraction.

Femtosecond laser-assisted cataract surgery (FLACS) uses a precision laser to perform the capsulotomy, lens fragmentation, and corneal incisions with computer-guided accuracy — reducing phacoemulsification energy requirements and potentially improving capsulotomy consistency for premium IOL centration.

At Moolchand Hospital in Lajpat Nagar Delhi, our experienced cataract surgeons perform phacoemulsification surgery using the latest phacoemulsification platforms, with comprehensive pre-operative biometry and IOL power calculation ensuring precise refractive outcomes, and detailed counseling to help each patient select the most appropriate IOL for their lifestyle and visual goals.
