Intraocular Light Scatter in Eyes With the Boston Type 1 Keratoprosthesis

Purpose:
The Boston keratoprosthesis (KPro) is the most commonly used artificial cornea. It has been proven to be successful for severe corneal disease not amenable to keratoplasty. We have observed our patients reporting debilitating glare despite attaining good visual acuities. This motivated us to objectively measure light scatter in eyes with a KPro.
Methods:
Light scatter was measured in 21 eyes with the Boston type 1 KPro with a VA of 20/150 or better and was compared with 13 healthy control eyes using the Oculus C-Quant device (Arlington, WA). Eyes were also measured using an occluder contact lens.
Results:
Light scatter (quantified as the logS value) was significantly higher in the KPro group than in the control (2.34 ± 0.15 vs. 1.29 ± 0.17, P
