A New Day for Cataract Surgery


Designed to provide complete confidence in surgical outcomes.

What is an IOL?

An intra-ocular lens (IOL) is an artificial lens implanted in the eye to treat cataracts.


  • Most frequently performed outpatient surgery in the world.
  • Age related cataract is the leading cause of blindness.
  • Excellent surgeons, IOLs and surgical technology deliver great safety outcomes.
  • Patients, however, are frequently left with suboptimal vision because refractive power is difficult to predict.
  • Existing options to modify refractive power are limited, difficult and risky.


The perfect choice for all cataract patients

The HARMONI Modular IOL features a base component and an optic component that work together in elegant simplicity.  The base provides a solid foundation within the capsular bag and enables versatile control by securely receiving the optic component using traditional surgical tools.  Both components of the HARMONI IOL are injected through a micro-invasive clear corneal incision. The versatile design of the Harmoni IOL is intended to incorporate a variety of lens configurations to customize vision to the patients’ needs.

ClarVista Medical, based in Aliso Viejo, California is a leading developer of innovative products to treat challenging ophthalmic conditions. In 2012 and in conjunction with series A financing, ClarVista was spun out from Prospex Medical, a medical device incubator, to pursue the development of the HARMONI IOL.

Between 2012 and 2014, the company developed the first generation HARMONI system, conducted a thorough first-in-human clinical study and developed a broad portfolio of intellectual property. In 2015, the company closed on a series B financing of $14M which was used to develop the second generation HARMONI system, initiate a larger feasibility clinical trial and obtain CE mark. In 2016, the company completed an interim analysis in its feasibility clinical study, initiated several other clinical studies, and began preparation for a US pivotal IDE study.
