What we do

Pandorum’s Bio-inspired Corneal ‘ink’ can be used as ‘Liquid Cornea’ for therapeutic application and to ‘print’ Corneal lenticule for human implantation – to treat visual impairment due to corneal defect.

Why We Do It

The World Health Organization (WHO) estimates that corneal opacities (including trachoma) accounted for 7% of world’s blind population in 2010, making it the 3rd most common cause of blindness

  • Globally, 4.9 million suffers from bilateral corneal blindness and 23 million from unilateral (est.)
  • ~12.7 million waiting for a corneal transplant globally (Solomon, 2005)
  • Although cataracts and glaucoma (in the elderly) are more common causes of visual impairment, corneal blindness affects all age groups and is a leading cause of irreversible visual impairment
  • 20% of childhood blindness is estimated to be caused by corneal blindness impacting their development, with high regional variances from 2% to 50% education, future job opportunities and quality of life.
  • In India alone, bilateral corneal blindness: 1.2 million; Unilateral involvement 5-6 million. 25,000 to 30,000 new cases of blindness added annually.
  • India has deficient collection of only 44,806/ year. ~54% of donated corneas do not meet standards for transplant
  • Corneal surgeons sufficiently skilled for transplant 400-500 nationwide with less than 100 centers equipped to support transplant operations as per standards.

How we do it

Liquid Cornea

Pandorum’s ‘Liquid Cornea’ is a regenerative approach towards vision restoration through tissue engineering and scar-less wound healing. It is designed for a simple, minimally-invasive application procedure, to curtail the requirement of post-operative medication and care.

  • Liquid Cornea formulation is supported by bio-inspired hydrogel scaffold and specialized stem cells. Fig. A (Extra Cellular Matrix (ECM)-mimetic petaloid microparticle) and Fig. B (Scanning Electron Microscopy (SEM) images of cornea decellularized ECM showing collagen fibrils)



  • The combination of specialized stem cells and bio-mimetic gel promotes scar-less wound healing and clears up the opaque tissue and restore patient’s vision. Fig. C corneal cells in a commercially available tissue sealant express alpha-smooth muscle actin protein, in green, a component of scar tissue, which is minimized in Liquid Cornea in Fig. D



Bio-printed Cornea

Pandorum’s proprietary ‘bio-ink’ can be used to print transparent and suturable Corneal lenticules embedded with live corneal cells
