“…9,10 Because of improvements in design and postsurgical management, the use of keratoprosthesis devices and, in particular, the Boston type 1 keratoprosthesis, has increased substantially in recent years. [11][12][13][14][15][16][17] The multicentre Boston type 1 keratoprosthesis study and several recent series have documented success of the Boston type 1 keratoprosthesis, in regard to both retention rate and visual outcomes. [18][19][20][21][22][23][24][25][26] Traditionally advocated for use in patients with profound vision loss in both eyes, recent successful outcomes in patients with preserved vision in the fellow eye have argued for the expansion of its indication.…”

“…Advances in type I BKPro design have improved its retention rate. The latest version approved by the Food and Drug Adminis tration (FDA) for marketing presents 8 holes of 1.3 mm diameter in the back plate to allow aqueous nutrition for the corneal button sandwiched between the front and back plate, protecting the tissue from necrosis and melt (2,9) . Moreover, the addition of a titanium locking ring, on the portion of the front plate protruding from the back plate, helps to prevent latter intraocular unscrewing of the BKPro complex.…”

Regardless of significant progress in the field of corneal transplantation to treat cor neal opacification, some cases of corneal blindness still present a poor prognosis for conventional penetrating keratoplasty. In patients with repeated graft fai lure and/or with severe ocular surface disease, the Boston type I keratoprosthesis (type I BKPro) has become a viable option. Modifications in its design and postoperative management have improved the longterm outcomes of visual acuity, retention, and postoperative infection rates. These advances made the type I BKPro be considered a safe alternative for visual rehabilitation in many patients with corneal pathologies. However, postoperative handle of chronic comorbidities, such as glaucoma, is still critical for preserving the visual gains achieved with BKPro.

“…9,10 Second, in 2004, a titanium locking c-ring was added to prevent intraocular disassembly of the device. Third, in 2007, the design was changed from a threaded (screw-type) assembly to a threadless design which simplified assembly and produced less damage to the donor endothelium.…”

“…Life-long topical steroids is necessary in all KPro eyes to prevent inflammation. 10,14 Also, the addition of 5% povidone iodine washes were added in each checkup with patients having high risk of endophthalmitis as well as those with a single eye, self-immune diseases or previous endophthalmitis history.…”

Background: Diseases affecting the cornea are a major cause of blindness all over the world, second only to cataract in overall importance. In India, there are approximately 6.8 million people who have corneal blindness with vision less than 6/60 in at least one eye, and of these, about 1 million have bilateral corneal blindness.Methods: The study was conducted in upgraded department of ophthalmology, L.L.R.M. Medical College, Meerut, India from January 2014 to June 2015. It was prospective interventional study. Included those patients who have Failed corneal graft with poor prognosis for further grafting, multiple corneal graft failure, having nearly total corneal neovascularization, vision less than 6/60 with associated other complications in better eye and no vision in opposite eye and Healed Chemical burn and those patients who has end stage glaucoma or RD (retinal detachment), defective perceptions and projection of light and not willing for the procedure.Results: A total of 20 patients were enrolled for the study which were followed up and assessed over 12 months. It was observed that maximum number of patients were in the age group of 41-60 years (45%) and in the >60 years group are minimum (20%). Among these 14 cases (70%) were male and 6 cases (30%) were female.Conclusions: The Boston type 1 keratoprosthesis provides visual recovery for eyes with multiple PK failures or with poor prognosis for primary PK, showing excellent retention rates. Most of the cases had a significant improvement in vision after Boston type I KPro implantation.
