AFFILIATED EYE SURGEONS | CORNEAL CARE
Corneal Transplant Surgery in Northern New Jersey
Fellowship-trained corneal surgery for Fuchs dystrophy, advanced
keratoconus, and other corneal conditions — using the latest DMEK, DALK, and PKP techniques at three convenient Northern New Jersey
locations.
Advanced Corneal Surgery When It's Needed Most
For patients with Fuchs endothelial dystrophy, corneal scarring, or advanced keratoconus that can no longer be managed with contact lenses or medications, corneal transplant surgery offers a path to restored vision. Modern corneal transplantation has advanced dramatically over the past two decades — today's procedures are more precise, safer, and recover more quickly than the full-thickness transplants of the past.
At
Affiliated Eye Surgeons, our corneal specialist
Dr. Sanjai Jalaj performs the full spectrum of corneal transplant procedures — from the latest lamellar (partial-thickness) techniques to full-thickness keratoplasty for complex cases. If you have been told you may need a corneal transplant, or if you are seeking a second opinion on your corneal condition, our team will provide a thorough evaluation and help you understand all of your options.
What Is Corneal Transplant Surgery?
A corneal transplant — also called keratoplasty — is a surgical procedure in which a diseased, damaged, or clouded cornea is replaced with healthy donor corneal tissue from an eye bank. The cornea is the clear front window of the eye, responsible for focusing incoming light onto the retina. When the cornea becomes significantly clouded, scarred, or structurally impaired, a transplant can restore the clarity and function needed for clear vision.
Modern corneal transplantation has moved away from the traditional full-thickness approach toward targeted lamellar (layer-specific) techniques that replace only the diseased layer of the cornea. This advances patient outcomes significantly — faster healing, better vision, and lower rejection risk compared to full-thickness transplants. The right procedure depends entirely on which layer of the cornea is affected and the nature of the underlying disease.
Conditions That May Require a Corneal Transplant
Corneal transplantation is indicated when the cornea has become too damaged or diseased to respond to non-surgical treatments. The most common conditions our team treats surgically include:
Fuchs Endothelial Dystrophy
A progressive hereditary condition in which the endothelial cells on the inner surface of the cornea gradually deteriorate, causing the cornea to swell and vision to become increasingly blurry and hazy. Fuchs dystrophy is the most common indication for corneal transplantation in the United States. DMEK is the gold standard treatment.
Bullous Keratopathy
Corneal swelling and blister formation resulting from endothelial cell failure, often following cataract surgery, glaucoma surgery, or other eye procedures. DMEK or DSAEK can restore clarity in these cases.
Advanced Keratoconus
When keratoconus has progressed to the point where the cornea is severely scarred or so irregular that specialty contact lenses can no longer provide functional vision. DALK is the preferred surgical approach for most keratoconus patients who require transplantation.
Corneal Scarring from Infection or Injury
Scarring caused by herpes simplex keratitis, bacterial keratitis, chemical burns, or traumatic injury can permanently cloud the cornea. The appropriate transplant procedure depends on the depth and extent of the scarring.
Corneal Stromal Dystrophies
Hereditary conditions such as lattice, granular, or macular dystrophy that cause progressive clouding of the corneal stroma, eventually requiring partial or full-thickness transplantation.
Failed Prior Corneal Transplant
Patients whose previous transplant has failed due to rejection, endothelial decompensation, or other causes may be candidates for regrafting.
Types of Corneal Transplant Surgery
The cornea has five distinct layers. Modern surgical techniques target the specific layer — or layers — that are diseased, preserving as much of the patient's own healthy tissue as possible. Your surgeon will recommend the most appropriate procedure based on the nature and extent of your corneal disease.
DMEK — Descemet Membrane Endothelial Keratoplasty
DSAEK — Descemet Stripping Automated Endothelial Keratoplasty
DALK — Deep Anterior Lamellar Keratoplasty
PKP — Penetrating Keratoplasty (Full-Thickness Transplant)
DMEK is the most advanced and precise endothelial transplant technique available. It involves removing and replacing only the innermost cellular layer of the cornea (the Descemet membrane and endothelium) — a tissue graft approximately 10 to 15 microns thick, which is thinner than a human hair. The donor tissue is carefully prepared, rolled into a scroll, inserted through a small incision, unrolled inside the eye, and positioned against the cornea using an air bubble.
DMEK offers the fastest visual recovery, best final visual acuity, and lowest rejection risk of any corneal transplant technique. Most patients see significant improvement within days to weeks rather than months. DMEK is the preferred procedure for Fuchs dystrophy and other endothelial diseases where the deeper corneal layers remain healthy.
Key advantages of DMEK:
- Fastest visual recovery of any transplant type — many patients notice improvement within days
- Lowest rejection rate — approximately 1% due to the minimal amount of foreign donor tissue
- Best final visual outcomes — most patients achieve 20/20 or better with glasses
- Small incision — no sutures required in most cases, reducing astigmatism
- Preserves the patient's own corneal surface and stroma — only the diseased inner layer is replaced
DSAEK was the predecessor to DMEK and remains a reliable option for endothelial transplantation. It involves removing and replacing a slightly thicker layer of posterior corneal tissue (including the stroma as well as the endothelium). DSAEK is technically easier to perform than DMEK and may be preferred in certain complex cases, such as eyes with previous glaucoma surgery, very small pupils, or other anatomical challenges that make DMEK technically difficult.
Visual outcomes with DSAEK are generally very good, though slightly less sharp than DMEK. Rejection rates are somewhat higher than DMEK due to the greater amount of donor tissue. Recovery is somewhat slower — typically 3 to 6 months for most of the visual improvement.
DALK is the preferred surgical treatment for conditions affecting the front layers of the cornea — most commonly advanced keratoconus and corneal stromal scarring. In DALK, the surgeon removes the corneal epithelium and stroma (the front layers) down to the level of Descemet membrane, while preserving the patient's own healthy endothelium (inner cell layer). Healthy donor tissue replaces the removed layers and is secured with sutures.
Because the patient's own endothelium is preserved, DALK carries significantly lower rejection risk than full-thickness PKP. There is no risk of endothelial rejection — the only foreign tissue is the donor stroma, which is immunologically less reactive. DALK is technically more challenging than PKP and requires an experienced corneal surgeon, but the outcomes and safety profile make it the procedure of choice for eligible keratoconus patients.
Key advantages of DALK:
- Lower rejection risk than PKP — no endothelial rejection possible
- Preferred for keratoconus — preserves the patient's healthy inner corneal layer
- Sutures can be removed over time to optimize vision and reduce astigmatism
- If rejection does occur, it affects only the donor stroma — generally treatable without losing the graft
PKP is a full-thickness corneal transplant in which the entire cornea — all five layers — is removed and replaced with a full-thickness donor button. PKP was the standard corneal transplant technique for decades and remains an important procedure for cases where all layers of the cornea are diseased or where the anatomy makes lamellar techniques technically impossible.
PKP has excellent long-term outcomes but involves a longer, more complex recovery than lamellar procedures. Sutures remain in place for 12 to 18 months or longer, during which time vision gradually improves. Rejection rates are higher than lamellar techniques (approximately 10 to 20% over the lifetime of the graft), and the graft requires lifelong monitoring. Despite these considerations, PKP remains the appropriate choice for many patients with complex corneal disease.

What to Expect: Corneal Transplant Recovery
Recovery timelines vary significantly depending on the type of transplant performed. Here is a general overview of what most patients experience:
DMEK Recovery
- Days 1-7: Vision may be blurry while the graft attaches and the air bubble is absorbed. Face-down positioning for several hours after surgery helps the graft adhere.
- Weeks 1-4: Vision begins improving as the endothelial cells become active and corneal swelling resolves. Many patients notice significant improvement within the first 1-2 weeks.
- Months 1-6: Most of the visual recovery occurs during this period. Many DMEK patients achieve 20/20 or better within 3-6 months.
- Long-term: Annual follow-up visits monitor endothelial cell health and graft function. Extended steroid drops reduce rejection risk.
DALK and PKP Recovery
- First weeks: Vision is blurry and light-sensitive as the eye heals. Activity restrictions apply — avoid heavy lifting, rubbing the eye, or contact sports.
- Months 1-6: Vision gradually improves as the cornea heals. Suture adjustment or selective suture removal helps reduce astigmatism over time.
- Months 6-18: Continued visual improvement as sutures are progressively removed. A stable glasses or specialty lens prescription cannot be given until the cornea has fully stabilized.
- Long-term: Annual follow-up for life. Steroid drops are continued long-term to minimize rejection risk. Scleral lenses are often fitted once the cornea has stabilized to maximize visual acuity.
Why Choose Affiliated Eye Surgeons for Corneal Transplant Surgery?
Fellowship-Trained Corneal Surgeon —
Dr. Sanjai Jalaj
Corneal transplantation is highly specialized surgery that demands deep expertise in corneal anatomy, disease management, and microsurgical technique. Dr. Sanjai Jalaj brings fellowship-level training in corneal diseases and keratoplasty to every transplant procedure. His experience spans the full range of modern techniques — DMEK, DALK, DSAEK, and PKP — and he has performed these procedures in complex cases including failed prior transplants and eyes with multiple prior surgeries.
Comprehensive Pre-Operative Evaluation
Corneal transplant surgery is never undertaken without a thorough pre-operative workup. Every surgical candidate undergoes detailed corneal topography, tomography, pachymetry, and specular microscopy (endothelial cell count) to characterize the disease, confirm surgical candidacy, and select the most appropriate procedure. We review your full ocular and medical history to ensure you are well-prepared for surgery and its recovery.
Full Spectrum of Transplant Techniques
Not every corneal surgeon performs the full range of transplant procedures. Offering DMEK, DSAEK, DALK, and PKP within the same practice means your procedure is selected based purely on what is best for your eye — not limited by the surgeon's available technique set. Patients referred to us for complex cases benefit from this breadth of surgical expertise.
Integrated Post-Transplant Care
The success of a corneal transplant depends as much on what happens after surgery as on the procedure itself. Our team provides structured long-term follow-up — monitoring graft health, managing steroid therapy, removing sutures at the appropriate time, and fitting specialty contact lenses once the cornea has stabilized. For keratoconus patients who undergo DALK, we coordinate seamlessly with our scleral lens fitting program to optimize post-operative vision.
Three Convenient Locations
Pre-operative evaluations and all post-operative follow-up care are available at our offices in
Morristown,
West Orange, and
Denville. Surgical procedures are performed at a nearby accredited ambulatory surgery center.
Frequently Asked Questions
What is a corneal transplant?
A corneal transplant (keratoplasty) is a surgical procedure in which a diseased, damaged, or clouded cornea is replaced with healthy donor corneal tissue from an eye bank. The cornea is the clear front surface of the eye, and when it becomes significantly clouded, scarred, or functionally impaired, a transplant can restore clear vision. Modern techniques allow surgeons to transplant only the specific layer of the cornea that is diseased, rather than replacing the entire cornea as was once required.
What conditions require a corneal transplant?
The most common conditions requiring corneal transplantation include Fuchs endothelial dystrophy, bullous keratopathy from prior eye surgery, advanced keratoconus where the cornea has become too scarred or irregular for specialty contact lenses, corneal scarring from infection or injury (such as herpes simplex keratitis), corneal stromal dystrophies, and failed prior corneal transplants requiring regrafting.
What is the difference between DMEK, DALK, and PKP?
These are three different corneal transplant techniques for different conditions. DMEK (Descemet Membrane Endothelial Keratoplasty) replaces only the innermost cell layer of the cornea and is used for Fuchs dystrophy and endothelial failure — it offers the fastest recovery and lowest rejection risk. DALK (Deep Anterior Lamellar Keratoplasty) replaces the front layers while preserving the patient's own healthy inner layer — preferred for keratoconus and corneal stromal disease. PKP (Penetrating Keratoplasty) replaces the full corneal thickness and is reserved for the most complex cases where all layers are diseased or damaged.
How long does corneal transplant surgery take?
The surgical procedure typically takes 1 to 2 hours depending on the transplant type and complexity. DMEK and DSAEK procedures are generally faster than DALK or PKP. Patients should plan to be at the surgical facility for several hours total including pre-operative preparation and post-operative monitoring. Most corneal transplants are performed as outpatient procedures under local anesthesia with IV sedation.
How long does it take to recover from a corneal transplant?
Recovery varies significantly by transplant type. DMEK patients often notice improved clarity within days to weeks and achieve most of their visual recovery within 3 to 6 months. DALK and PKP recoveries are longer — full visual stabilization may take 12 to 18 months or longer, particularly as sutures are gradually removed. All transplant patients require extended post-operative eye drops, typically for one year or more, and regular follow-up visits to monitor healing and rejection.
What is corneal transplant rejection and how common is it?
Corneal transplant rejection occurs when the body's immune system attacks the donor tissue. Symptoms include sudden vision decrease, eye redness, light sensitivity, and pain — and should be treated as a medical emergency. Rejection rates vary by procedure: DMEK has the lowest risk at approximately 1%, while PKP carries a higher lifetime risk of 10 to 20%. Long-term steroid eye drops significantly reduce rejection risk. When identified and treated promptly, most rejection episodes can be reversed without losing the graft.
Will I need glasses or contact lenses after a corneal transplant?
Most patients will need some form of vision correction after transplantation. Following DMEK for Fuchs dystrophy, many patients achieve very good vision with glasses alone. Following DALK or PKP, the transplanted cornea often has residual irregular astigmatism, and specialty contact lenses — particularly scleral lenses — may be needed to achieve the best vision. A final prescription is not given until the cornea has fully stabilized and sutures have been removed, which can take 12 to 18 months.
How long does a corneal transplant last?
Modern corneal transplants are highly durable. DMEK grafts have excellent long-term survival, with the majority functioning well for 10 to 20 years or longer. DALK and PKP grafts also have good longevity when managed properly with appropriate post-operative care and monitoring. Some patients may eventually require a repeat transplant if donor cells gradually decline over time. Regular follow-up appointments allow early identification of any graft health concerns.
Is a corneal transplant the right option for my keratoconus?
The vast majority of keratoconus patients do not need a corneal transplant. Most patients manage effectively with specialty contact lenses for vision correction and corneal cross-linking to halt progression. Corneal transplantation for keratoconus — typically DALK — is reserved for patients with advanced disease who have significant corneal scarring or can no longer achieve functional vision with specialty lenses. If you are concerned about your keratoconus progressing toward transplantation, a comprehensive evaluation at Affiliated Eye Surgeons is the right next step.
