Patient: The child is currently 14 years old and was born in November 1995. In April 1996, Pseudomonas aeruginosa infection caused a corneal ulcer, and after one month of treatment, the cornea was perforated and posterior corneal staphyloma was observed. In September 1996 and December 1996, he underwent two ciliary cryosurgeries at the Eye, Ear, Nose and Throat Hospital of Fudan University in Shanghai, which improved the corneal staphyloma and has continued to do so since. At present, the eye is not atrophied but the cornea is irregularly elevated and I cannot wear colored contact lenses or thin prosthesis. I would like to ask the doctor if it is possible to do corneal transplantation or cryosurgery or a modified conjunctival flap to cover the whole cornea, so that the corneal bulge can be improved, and then try to wear colored contact lenses to achieve cosmetic results, or what other cosmetic solutions are available, I look forward to it! A: After conjunctival flap masking total keratoplasty, you can only wear prosthetic eyes, not tinted contact lenses. If the eye is not a little atrophied, wearing a prosthetic eye after conjunctival flap masking total keratoplasty will make the eye appear more prominent than the healthy eye (thin prosthetic eyes are also of a certain thickness). Corneal transplantation does not improve vision, so there is no need to spend so much money. Cryosurgery cannot definitely reduce IOP. You can’t see how big the grapheme is in the photo, but you can also try a modified conjunctival flap to cover the whole cornea if it’s not too big. If you can accept the removal of the eye, it is better to have a table implant, because the staphyloma will continue to develop, and if it develops after covering the inside, the eye will still need to be removed. Patient: I would like to ask Dr. Min what are the complications of these prosthetic eye table implants? 1. infection. 2. Tissue incompatibility and rejection, necessitating surgical removal of the prosthesis. 3. Prosthesis exposure occurs. 4. The implanted prosthesis is immobile or has poor mobility. 5. The prosthesis is displaced. 6. Conjunctival thinning and conjunctival damage. 7. Ptosis or failure to close the upper eyelid. 8. 8. Atrophy of the intraocular and peripheral fatty tissues usually starts to occur six months after the implantation of the prosthesis, with varying degrees of depression in the upper eye socket. The degree of atrophy gradually increases with time. 9. After 15 years of implantation, the material of hydroxyapatite prosthesis becomes loose due to the vascularization problem, and the prosthesis may shatter under slight force. It is extremely painful for the patient to remove the prosthesis, so hydroxyapatite prostheses are now rarely used in Europe. Patient: We don’t want to remove the eye because there are many complications and risks, and the child can’t accept this surgery. A: Freezing can make the eye shrink, but not make the grapevine swelling better. The wall of the eye is very thin where the grapevine swelling is, and there is a risk of perforation if it develops.
