Doctor Education & CE Courses
Lectures, surgical films, and live continuing education by Dr. Lawrence Tenkman on cataract, cornea, and glaucoma surgery. Made for optometrists and eye care professionals; videos contain surgical footage.
Teaching is part of who we are.
2025 KOA Optometric Educator of the Year · First recipient
Through its founder, Legacy has a long history in ophthalmic education. Fighting blindness at scale takes a well-educated community and a strong surgical home. Community eye doctors know when to escalate; within our practice, residency-trained optometrists form the front line and our surgeons stand behind them.
EyeNinja live CE
Legacy is a COPE Administrator. Dr. Tenkman's EyeNinja series is a living, engaging course on anterior-segment surgery and key conditions, offered in person and live virtually for CE credit. We look forward to partnering with optometry schools.
Residents and fellows
We work with residency and fellowship programs, and EyeNinja films have won multiple ASCRS Film Festival awards, putting many residents on the field's biggest stage. A comprehensive anterior-segment fellowship is planned. The world needs more sub-specialists; we look forward to training them.

Cataract Preop
Cataract surgery varies from simple to quite complex. How to use the preoperative exam to get the best possible outcomes.
Cataract Intraop
A surgical tour of cataract surgery in the operating room, from routine to complex, including damaged zonule and capsule cases and sutured IOLs.
Cataract Postop
Basic postoperative care after cataract surgery, plus lesser-known pearls for taking the best care of patients.
Cornea Transplants
The principal types of corneal transplants: PK, DALK, DMEK, and DSAEK.
Cornea Crosslinking
A stretched-out cornea can be ruined, and transplants are not a quick or perfect fix, so recognizing ectasia early and preventing it from worsening is paramount.
Cornea Surface Disease, Part 1 (Growths)
Pterygia, Salzmann nodules, surface cancers, and epithelial ingrowth, from routine cases to very unusual ones.
Cornea Surface Disease, Part 2 (Insufficient Growth)
Neurotrophic keratitis and corneal epithelial stem cell deficiency, when the cornea loses its protective epithelial barrier.
Glaucoma Surgery
Emergency procedures like paracentesis and wound burps, MIGS procedures in the operating room, and fistulizing surgeries such as XEN and glaucoma tubes.
Key Glaucoma Lasers
The big pitfalls to avoid with glaucoma lasers, and why compressive gonioscopy is a must.
8:00Crouching Tiger, Hidden Fragment 2: Search & Destroy
How to suspect, find, and remove hidden cataract fragments after cataract surgery, illustrated with several cases.
8:01Ninja Finger
Most patients love modern multifocal IOLs, but around 1% never adapt. Recognizing and managing multifocal intolerance.
8:01Lock & Load: Injection for Infection
Treating endothelial-side corneal ulcers with stromal injection in the operating room.
26:46Ninja K-Pro
A keratoprosthesis offers hope of restoring vision where traditional surgery would fail.
Floss Your Eye! (Ninja KPro 3)
A technique borrowed from dentistry to clean debris from under the rim of a KPro, to prevent inflammation and infection.
Ninja KPro 2
Very unhealthy eyes can melt and perforate the corneal tissue of a KPro if it is ever left uncovered by conjunctival epithelium.
Ninja KPro 2: Follow-Up
In unstable eyes, the flap needs close follow-up and revision until it scars into place with full corneal coverage.
DMEK Preparation (2014)
DMEK graft preparation using modifications to the Giebel SCUBA technique.
DMEK Insertion (2014)
DMEK insertion strategies: host preparation, insertion, and opening, using modifications to the Giebel microbubble technique.
Dead Bag Multifocal (Suture Any IOL 3)
Dead bag syndrome with a multifocal IOL: the bag and zonules disintegrate over time and the IOL decenters. How can it be saved?
Flange Loops: Perfect Centration & Rotation (Suture Any IOL 2)
7-0 Prolene with 30-gauge ultra-wide lumen needles to save a dislocated in-the-bag IOL, with tips for ideal centration and rotation.
8:00No Retreat, No Surrender: Suture Any IOL
A complication ruins the bag when a multifocal high-power toric IOL was planned. What now?
8:00Sulcus Sabotage: Plan a PI for Your Posterior Partner
Posterior capsule openings, a 3-piece sulcus IOL, optic capture when possible, and planning a PI.
8:00Crouching Tiger, Hidden Fragment
How much "rebound inflammation" is really inflammation from hidden retained cataract fragments? They occur more often than we realize.
Peekaboo Foreign Body
Can foreign bodies behave like cataract fragments, hiding in the sulcus and then appearing in the inferior angle? Apparently, yes.
8:00Death Dive: The Dual Ripcord Baerveldt
A Baerveldt glaucoma tube placed with two ripcord sutures.
Glaucoma Tube Touching Endothelium & Scar Growing into Ahmed Valve
Long scleral tunnels can avoid the need for a patch graft.
GSL When the View Is Bad (Goniosynechialysis)
A narrow angle undetected until angle closure, with significant edema. How to handle angle synechiae and avoid a "perfect storm" after a PI.
8:39Danger in the Dark (Extended Version)
When visibility drops during surgery, a handheld slit beam helps: AC shallowing from acute misdirection, tube checks and more.
Tube Hyphema From Hell
A monocular end-stage glaucoma patient with a severe hyphema and a high pressure spike.
12:33Perfect Storm
A pressure spike best avoided, with pearls on goniosynechialysis and the value of gonioscopy.
