Inclusion criteria

Inclusion criteria: Observation group: subjects were recruited for the study from the general pool of patients seeking cataract surgery. Patients included those with an axial eye length > 28 mm when measured using the IOLMaster (Carl Zeiss, Germany. Validation group: subjects were recruited for the study from the general pool of patients seeking cataract surgery. This group included patients for which the long axis of the eye could not be measured using the IOLMaster. Patients included those with an axial eye length > 28 mm measured using A ultrasound.

Exclusion criteria

Exclusion criteria: Patients with eye trauma, corneal and/or retinal disease, or a previous history of eye surgery were excluded from the study.
