The use of an optical biometer for biometric measurements led to accurate IOL power calculations for several IOL power formulas.
The prospective interventional multicenter study included 118 eyes of patients undergoing cataract surgery. Researchers evaluated results of IOL power calculations using different corneal power measurements provided by an optical biometer combined with a Scheimpflug analyzer and Placido disc topographer. The formulas used were Barrett Universal II, Haigis, Holladay 1, SRK/T and Hoffer Q. Additionally, simulated keratometry and total corneal power were used to
