LASIK eye surgical procedure – a laser reshaping of the cornea to enhance imaginative and prescient – is likely one of the hottest elective surgical procedures in the USA, and a College of Houston professor of biomedical engineering intends to enhance upon it by giving surgeons extra details about the cornea earlier than they start.
Particularly, Kirill Larin desires to offer measurement of corneal elasticity, a key part of visible acuity. Eye surgeons at the moment wouldn’t have a dependable technique to carry out a quantitative measurement of corneal elasticity in sufferers earlier than the process.
“We’ll develop a novel technique for the imaging and evaluation of corneal elastic properties that might probably be used for routine medical diagnostics of various corneal illnesses and therapy,” stated Larin, who’s utilizing a $1.6 million continuation grant from the Nationwide Eye Institute to enhance present Optical Coherence Tomography (OCT) to offer ultrafast 3D medical imaging. The know-how will mix Brillouin microscopy with Optical Coherence Tomography (OCT) and Optical Coherence Elastography (OCE) – creating the brand new BOE.
The brand new BOE know-how makes use of extremely localized air strain stimulation.
We will use an air puff that may produce very small waves on the floor of the attention. The affected person won’t really feel them, however we will detect them. The pace of the waves will inform us concerning the elasticity of the cornea.”

Utilizing OCT, he’ll reconstruct volumetric biomechanical properties of the cornea.
Larin already developed a primary prototype of the mixed instrument, demonstrated its functionality to measure biomechanical properties of the cornea in vitro and in vivo, and has developed analytical fashions to extract biomechanical properties. The brand new grant, he stated, will speed up transition of this know-how into clinics, affect the choice and software of corneal surgical therapies and can assist perceive the structural penalties of corneal illness and wound therapeutic.
Larin’s earlier work made basic advances within the understanding of corneal biomechanics, which affect medical interpretation of diagnostic assessments, e.g. measurement of intraocular strain, and have been implicated as essential components within the improvement of glaucoma.
“Our know-how will optimize the supply of well being care to the attention and ship an early prognosis for a lot of eye circumstances.”
