The partial coherence interferometry-based biometers segment is expected to register the fastest CAGR over the forecast period as optical biometry using partial coherence laser interferometry (PCLI) offers advantages in accuracy and reproducibility of axial length (AL) determination as well as are more comfortable for the patient and the investigator as compared to conventional ultrasonic biometry.
In situations where Optical Biometry is not available or accessible; immersion biometry is a good choice but certainly not the applanation Biometry.
Firstly, IOL constants, provided by the manufacturer, are mostly estimated for contact biometry.
So it should be noted that non-contact imersiona and optical methods give axial lengths slightly larger due to the absence of corneal indentation.

IOLs may require surgical correction due to complications of previous cataract surgery, late IOL subluxation, or inaccurate biometry.
This risk is higher in patients with factors like PEX, previous vitreoretinal surgery and trauma.
A complete ophthalmologic exam was conducted, including neuro-ophthalmic reflexes, Schirmer tear test I (STT-I), intraocular pressure (IOP) using rebound tonometry, fluorescein staining, horizontal corneal measurements using Jameson calipers, direct and indirect ophthalmoscopy, and ocular ultrasound biometry.
Eyes with an STT of <5 mm/min, outliers, and eyes with severe diseases were excluded from reference value analysis.

Optimal management of pregnancy relies on accurate assessment of the gestational age (GA) of the fetus; which can be determined by the history of the last menstrual period (LMP), clinical estimation of the 1st symphysis-to-fundal height measurement (FH) or ultrasonographic fetal biometry.
However, many women fail to recall their LMP accurately.
Visitor Management System-Visitor management system is a system for authentication of human identity using facial biometry.
These studies reported that optical systems give more accurate and reliable results than US biometry.
