What Does Biometry Help With?

Biometry supports the consistent measurement of the eye’s internal structures, helping deliver critical data for precise assessment and surgical planning. Optical biometry is most commonly used in cataract evaluation and assessment, where precision measurements such as axial length, corneal curvature, corneal thickness, anterior chamber depth (ACD) and lens thickness are essential. This allows for accurate intraocular lens (IOL) calculation when planning surgery.

 

In their delivery of fast, repeatable measurements, optical biometers help improve surgical predictability, particularly in complex cases. They support ophthalmologists in pre-operative assessment, post-operative review and decision-making around referrals, ensuring effective patient care. Reliable biometry depends not just on the technology, but on consistent performance, correct calibration and long-term technical support, all of which are provided by Mainline Instruments and our expert team.

Frequently Asked Questions

What is optical biometry?

Optical biometry is the non-invasive measurement of the eye’s internal structures, including axial length, corneal curvature, corneal thickness and anterior chamber depth. It is primarily used in cataract assessment and intraocular lens (IOL) calculation to support surgical planning.

The ability for patients to measure their own IOP has the potential to transform glaucoma care. By using home monitoring, we can obtain far more IOP measurements to more accurately identify peak IOP and gain greater appreciation of IOP fluctuations.

Most patients find iCare HOME easy to use and as IOP measurements can be uploaded to the cloud, the clinician can view results remotely. In my practice, the introduction of iCare HOME has allowed us to move away from office-hour IOP phasing and has provided improved insight into IOP as a risk factor for glaucoma progression.
