i-Optics starts major sales push for its corneal topographer system

Investors certainly seem happy enough with the progress of the Netherlands-based ophthalmic diagnosis company, I-Optics, which this week has unveiled a corneal topographer system, called Cassini, that is designed to detect higher order aberrations with far better precision and accuracy than with ring topographers. The release took place at the the annual meeting of the British Contact Lens Association and follows the completion of a series D financing round that resulted in the company’s coffers increasing by EUR .7 million.
Specifically aimed at expanding the market for multifocal, toric, aspheric and ortho-k contact lenses, the system aims to meet the challenges of opticians and optometrists in ensuring accuracy in fitting such devices in patients with premium contact lenses. The unveiling also follows on from another tipped for 2012 growth development, namely the EasyScan non-mydriatic retinal imaging system, which was released in late 2011.
Cassini is based upon colour LED topography (CLT), which has been developed with the Amsterdam VU Medical Centre and replaces the rings used in Placido topographers with 672 colour-coded LEDs set in a pattern, thereby offering superior precision and accuracy, also for dry eyes and irregular corneas. The technology can measure high and low order aberrations precisely and in any direction, in contrast to Placido topographers that are limited to accurate measurements in a radial direction. Further refinements of the technology could potentially include early keratoconus detection and progression monitoring, cataract and refractive surgery and LASIK surgery.
Keratoconus affects approximately three million patients worldwide, and early diagnosis is key to ensuring the best possible treatment. The CLT could potentially detect the condition and other corneal irregularities due to to its ability to measure small aberrations with submicron accuracy and precision. The indication is currently being tested in a patient study being carried out at an undisclosed eye healthcare centre.
Longer term, it could also be possible to measure the power and shape of intraocular lenses (IOL) more precisely by combining Cassini’s CLT technology with further technology that measures the axial length, anterior chamber size and other parameters for IOL fitting. I-Flow says the current devices generate a post-op error of 0.5D, whilst using Cassini could reduce this to 0.2D and result in a smaller number of patients requiring glasses after the procedure.
