PK Comprises Largest Share of Keratoplasty Globally
PK made up the largest share of the corneal transplantation market in 2021, and is expected to produce the highest compound annual growth rate (CAGR) through to 2028, according to “Corneal Transplantation Market Forecast to 2028 – COVID-19 Impact and Global Analysis – Type, Indication, End User,” a study from The Insight Partners, an industry research provider. The market is segmented into single-use PK, Descemet’s membrane endothelial keratoplasty, Descemet’s stripping endothelial keratoplasty, and corneal limbal stem cell transplant, among others.
Christopher Rapuano, MD, chief of the Cornea Service at Wills Eye Hospital, in Philadelphia, says he believes there are two reasons PK leads in corneal transplantation type worldwide:
“First is the availability of EK tissue. It’s just not as available around the world as it is in the United States,” he explains. “Second, surgeons outside the United States aren’t necessarily trained to perform Descemet’s membrane endothelial keratoplasty or Descemet’s stripping endothelial keratoplasty.”
Additionally, the study showed Fuchs’ endothelial dystrophy was the No. 1 reason for keratoplasty in 2021 and is expected to provide a CAGR of 6.8% through to 2028. Further, hospitals were the places most keratoplasties occurred in 2021, and they are expected to register a CAGR of 6.8% through 2028.
In terms of the corneal transplantation market itself, it is expected to reach $640.79 million by 2028 from $420.71 million in 2021, and is expected to increase at a CAGR of 6.2% up to 2028, The Insight Partners study showed.
The reason behind this growth is a global surge in the geriatric population, particularly a subset of patients older than age 80, the study revealed. In looking at the United States, for example, 54.1 million people were aged 65 and older in 2019 (an increase from 39.6 million in 2009), reported the U.S. Department of Health and Human Services. Due to advanced age, this population experiences health issues, including ocular surface and corneal tissue aging, vision impairment, and ocular disease.

Music May Tame the Anxious Cataract Surgery Patient
Web app–based personalized music intervention prior to cataract surgery may lower anxiety levels and hypertension or decrease the need for sedative medication, reported a study in JAMA Ophthalmology.1
Specifically, the incidence of hypertension was significantly less in those who listened to web app–based personalized music (21 [13.6%]) vs those in the control group, who wore noise-cancelling headphones without music (82 [52.9%]), with a difference between the 2 groups of 39.3% (95% CI, 21.4%-48.9%; P < .001).
Additionally, the mean visual measure of anxiety was less in the web app–based personalized music group (1.4 [2.0]) versus in the control group (3.1 [2.4]), with a difference of 1.5 (95% CI, 1.0-2.1; P = .005).
Further, the mean number of sedative drug injections needed during the procedure was 0.04 (0.24) in the web app–based personalized music group versus 0.54 (0.74) in the control group who wore noise-cancelling headphones, with a difference of 0.50 (95% CI, 0.43-0.57; P < .001).
A total of 310 participants were randomized to each group (155 per group) 20 minutes prior to cataract surgery.

Increased Screen Use Creates Eye Strain and Convergence Insufficiency in Children
Wills Eye Hospital ophthalmologists found that heightened screen time translates to more eye strain and convergence insufficiency in children, confirming eye care providers’ prediction that virtual schooling would have a negative effect on children’s vision.
Specifically, the study, presented at this year’s American Academy of Ophthalmology Meeting, showed that the more time students ages 10 to 17 spent online, the increased likelihood they would experience eye strain and convergence insufficiency, with 57% noticing eye strain and 61% displaying symptoms of convergence insufficiency. Regarding the latter, 17% fell under severe cases.
The study was comprised of 110 students free of vision issues prior who were surveyed before and after virtual learning, which ranged between 3 to 10 hours.

FDA Green Lights Generic Version of Allergan/AbbVie’s Restasis
The FDA approved the first generic version of Allergan/AbbVie’s Restasis, which obtained the government entity’s nod as a brand close to 20 years ago for the increase of tear production in patients whose tear production is presumed suppressed from ocular inflammation linked with keratoconjunctivitis sicca. The sponsor of the approved generic cyclosporine ophthalmic emulsion 0.05% single-use vials was Mylan Pharmaceuticals, Inc.
In 2012, the FDA began research into supporting the creation of bioequivalence suggestions for Restasis as part of its Generic Drug User Fee Amendments Research Program, it said. To date, the government entity has supported 16 research projects associated with cyclosporine ophthalmic emulsion, it said.
National Science Foundation Awards $250,000 to Researcher to Create Adhesive for Corneal Repair and Grafting
The National Science Foundation granted $250,000 to Iman Noshadi, PhD, an assistant professor of bioengineering at UC–Riverside’s Marlan and Rosemary Bourns College of Engineering, to create a transparent adhesive that speeds healing and decreases the likelihood of secondary infection from corneal repair and grafting, reported UC–Riverside. Dr. Noshadi told the university he hopes the adhesive will be available by 2026.
![Dr. Iman Noshadi. IMAGE COURTESY UC RIVERSIDE](https://res.cloudinary.com/broadcastmed/image/fetch/q_auto,f_auto/dpr_auto/https://cornealphysician.com/media/om3jfuq3/n_4.jpg)
Specifically, the adhesive is comprised of a biodegradable polymer that merges organic salt with high-water solubility and electrochemical properties with polyethylene glycol, enabling long-term regeneration of corneal cells.
“Our gel will result in a safer procedure that will improve the patient’s quality of life with better health outcomes by preventing visual acuity loss or blindness,” Dr. Noshadi explained to UC–Riverside.
He added that it will save time, decrease operative costs, and exclude corrective surgery and the requirement for extensive postoperative care.
Additionally, Dr. Noshadi told UC-Riverside that his research group will assess the adhesive’s ability to stick, its antimicrobial properties, its biocompatibility, and its transparency before testing it on corneal tears and corneal cells.
Denmark Ophthalmologists and Mechanical Engineers Create Anterior Chamber Model to Aid in Corneal Transplantation
Department of Ophthalmology at Rigshospitalet’s eye specialists joined forces with Denmark Technical University (DTU) to create a model of the anterior chamber of the eye to help them determine new techniques for corneal transplantation, according to a press release issued by DTU.
Specifically, the model mimicked the anterior chamber’s pressure and temperature and flow of fluid to the back of the cornea and tear film, and it supported the postop phase during which the patient lies and then sits and stands up, so the ophthalmologists could observe the reaction of the cells on the posterior layer of the cornea post-transplant.
Javier Cabrerizo, MD, a clinical associate professor at the Department of Ophthalmology at Rigshospitalet, commented to DTU, “We’re looking forward to using the model in the department’s coming research, and I’ve no doubt at all that — in the long-term — it will benefit our patients that we now have this opportunity.”
University of Arizona College of Medicine–Tucson Researchers to Assess Role of Proteins in Cataract Development
Researchers at the University of Arizona College of Medicine–Tucson will be using a $1.6 million grant to assess the role of the TRPV1 and TRPV4 proteins in the development of cataracts, in hopes the research will lead to the creation of nonsurgical treatments, according to a press release issued by the school. The researchers, led by Nicholas Delamere, PhD, professor and head of the Department of Physiology, discovered that these proteins collaborate in a way that regulates the lens’ cell function, including water content, size, shape, optical clarity, and focusing power.
“Human cataract is frequently associated with failure of the mechanisms controlled by TRPV1 and TRPV4,” he explained in the press release. “The hope is that studies like this might pave the way to the development of strategies to prevent or delay age-related eye diseases.”
Specifically, the study will probe how tiny alterations in hydrostatic pressure in the lens’ surface cells activate TRPV1 and TRPV4 to make homeostasis possible. Additionally, the research team, which also consists of Mohammad Shahidullah, DVM, PhD, research associate professor in the Department of Physiology, and Rick Mathias, PhD, and Junyun Gao, PhD, of the Department of Physiology and Biophysics at Stony Brook University, hope to characterize the molecular association between the proteins and the cell’s interior framework, or cytoskeleton.

Australian Corneal Bioengineers to Create Bioengineered Tissue
Corneal bioengineers in Australia have joined forces to form a consortium, called BIENCO, that will create bioengineered tissue to meet the challenge of corneal blindness, according to a press release issued by the University of Melbourne, a member of the consortium. Other consortium members are the University of Sydney, University of Wollongong, Queensland University of Technology, Centre for Eye Research Australia, and the NSW Organ and Tissue Donation Service.
Specifically, BIENCO said it will create cost-effective individually tailored, superior corneas and partial grafts for transplant to decrease the amount of donor tissue needed.
“This will significantly improve cost-effectiveness and sustainability of corneal transplants in Australia and increase global access to vision-restoring corneal transplant surgery,” said Professor Gerard Sutton, the consortium’s lead and a corneal specialist at the University of Sydney Save Sight Institute, and co-medical director of an Australian tissue bank.
Scleral Lens and Prosthetic Replacement of the Ocular Surface Ecosystem Aid in Controlling Graft-versus-Host Disease Symptoms
Scleral Lens and Prosthetic Replacement (SL/PDs) of the Ocular Surface Ecosystem helped to manage the symptoms of graft-versus-host disease (GVHD) (e.g., gritty, dry eyes), reported a recent study in Clinical Ophthalmology.1
Specifically, wearing scleral lenses resulted in a mean of 5.42 ± 1.86, median (IQR) of 6.0 (4.0 to 7.0) symptoms improving, with the most common being dryness/grittiness of the eyes (94%), eye pain (92%), and quality of life (89%). Additionally, 56% of those wearing scleral lenses said they’d wished the lenses had been suggested sooner.
The study was comprised of 306 subjects registered with the Blood and Marrow Transplant Information Network, who answered a 15-question survey that reviewed transplant history, GVHD history, symptoms and onset, treatments employed, the amount of symptom control, and experience in SL/PDs.
