The Latest Advancements in Corneal Transplant Surgery
Hello Reader!
Welcome to the blog page of Pushpanjali Eye Care, one of the best eye vision clinic.
The cornea, the clear outermost layer of the eye, plays a critical role in focusing light onto the retina. Any cornea damage or disease can lead to significant vision impairment or blindness. However, with advancements in medical technology and surgical techniques, corneal surgery has radically transformed, offering new hope for patients. At Pushpanjali Eye Care, recognized as one of the best eye hospital in Kolkata, we are committed to staying at the forefront of these advancements to provide world-class eye care.
Corneal surgery involves procedures aimed at treating corneal diseases, injuries, or conditions like keratoconus, corneal scars, infections, and dystrophies. With the advent of innovative technologies, corneal surgeries are now less invasive, more precise, and have significantly improved patient outcomes.
The integration of femtosecond laser technology has revolutionized corneal transplantation and refractive surgeries. This technology allows surgeons to create precise incisions, leading to faster recovery and improved vision outcomes. At Pushpanjali Eye Care, we leverage this cutting-edge technology to ensure optimal results for our patients, reaffirming our reputation as one of the best ophthalmology clinic.
DMEK is a minimally invasive procedure that involves replacing only the damaged endothelial layer of the cornea. This technique offers faster visual recovery, reduced rejection rates, and a more natural optical result compared to traditional full-thickness transplants.
DSAEK is another advanced corneal transplant technique where a thin layer of donor corneal tissue, including the endothelial layer, is transplanted. It has become a standard for treating endothelial disorders, such as Fuchs’ dystrophy.
For patients who cannot benefit from traditional corneal transplants, artificial corneas (keratoprosthesis) offer a viable solution. This technology provides vision restoration to patients with severe corneal damage.
Corneal cross-linking is a non-invasive treatment primarily used for keratoconus. This technique strengthens the cornea by increasing collagen cross-links, preventing further thinning and distortion.
3D printing has opened new frontiers in corneal surgery. Scientists are now able to create biocompatible corneal implants using patient-specific data, potentially eliminating the dependency on donor tissue in the future.
Technologies like anterior segment OCT (optical coherence tomography) and Scheimpflug imaging have enhanced the precision of corneal surgeries. These diagnostic tools provide detailed images of the cornea, allowing surgeons to plan and execute procedures with greater accuracy.

Artificial cornea implantation has seen significant advancements aimed at addressing the global shortage of donor corneas and improving patient outcomes. With millions of individuals affected by corneal blindness, innovative solutions are being developed to provide effective alternatives to traditional corneal transplants. Here are some of the latest advancements in this field.
Researchers at Cardiff University have pioneered fully synthetic corneal implants designed to alleviate the shortage of donor tissues. These implants are made from collagen analogs, which not only simplify the manufacturing process but also reduce costs. Importantly, they are engineered to suppress inflammation and promote tissue regeneration, which is crucial for long-term success in patients awaiting transplantation. This development presents a promising alternative for those suffering from corneal diseases, as it mitigates the risks associated with immune rejection that often accompany traditional transplants.
Recent studies have introduced bioengineered corneal tissues that can be implanted using minimally invasive methods. One such innovation involves a cell-free engineered corneal tissue known as BPCDX, which can be inserted into an intrastromal pocket within the recipient’s cornea without removing existing tissue or using sutures. This technique has shown significant improvements in corneal thickness and visual acuity in clinical trials conducted in India and Iran, demonstrating outcomes comparable to standard corneal transplantation but with a simpler surgical approach.
The field of keratoprostheses (KPros) has also evolved, with new synthetic designs that enhance biointegration with native tissues. The AlphaCor™, a synthetic polymer keratoprosthesis, has been improved to minimize complications such as stromal melting and optic deposition. These advancements aim to create more durable and effective artificial corneas that can better replicate the natural structure and function of human corneas.
Innovative cell therapy techniques are being explored to reduce the need for donor corneas altogether. For instance, companies like Eversight are conducting clinical trials that involve injecting healthy donor corneal endothelial cells directly into the eye. This approach aims to repopulate diseased corneas with functional cells, potentially eliminating the need for transplantation. Such therapies could significantly increase the number of patients treated with just one donor cornea, addressing both supply issues and improving patient outcomes.
A new patented technology called Hygelix™ is being developed by researchers at the University of Melbourne in collaboration with Eversight USA. This innovative method enhances the adherence of donor corneal endothelium during transplantation, allowing it to “pop-up” like a tent when implanted. This technique is expected to improve surgical outcomes for patients undergoing corneal transplants and is currently undergoing pre-clinical trials.
Corneal transplantation, while generally considered a safe and effective procedure, carries several potential risks and complications that patients should be aware of. Understanding these risks is crucial for anyone considering the surgery, as they can impact both the short-term recovery and long-term success of the transplant.
One of the most significant risks associated with corneal transplantation is graft rejection. This occurs when the body’s immune system identifies the transplanted cornea as foreign and attempts to attack it. The incidence of rejection varies, with approximately 10-20% of patients experiencing some form of rejection after full-thickness corneal transplants. Symptoms may include redness, sensitivity to light, and cloudy vision. Fortunately, early detection and treatment with steroid eye drops can often reverse this condition if addressed promptly.
Infection is another potential complication that can arise post-surgery. This can occur due to bacteria, viruses, or fungi entering through surgical wounds. Post-operative infections can lead to serious complications, including endophthalmitis, which is an inflammation of the interior of the eye that can threaten vision. Patients are advised to monitor for signs of infection, such as increased pain, redness, or discharge from the eye.
Corneal transplantation can lead to elevated intraocular pressure, commonly referred to as glaucoma. This condition may develop due to inflammation or as a side effect of medications used during recovery. Secondary glaucoma was reported in about 13% of cases in some studies, making it a significant concern for postoperative management. Regular monitoring and treatment are essential to prevent damage to the optic nerve.
Patients who undergo corneal transplantation may also be at risk for developing cataracts, which is a clouding of the eye’s lens that can impair vision. This complication can occur due to the surgical procedure itself or as a side effect of corticosteroid medications used to prevent rejection.
Other potential complications include:
