ABSTRACT
Objective:
To investigate the accuracy of Immersion A-Scan Biometry by comparing the relationship between the predicted refractive status from the biometric data with the achieved refractive status determined from objective/subjective refraction. Design andMethodology:
Sixty patients were recruited from the Trinidad Eye Hospital (TEH) who was scheduled to undergo cataract surgery. The method of ocular biometry measurement used in this study was Immersion A-scan Biometry using the Aviso The Ultrasound Platform. The biometric data was then recorded along with the expected refractive status based on the SRK-T formula used to calculate the power of the intra-occular lens (IOL) to be implanted.Results:
Out of the 60 patients used, phacoemulsification surgery was performed on 33 right eyes and 27 left eyes. The goal of emmetropia after surgery was achieved in 32 patients among the 60 patients. The 28 patients that were unable to achieve emmetropia brought awareness to the assumptions of errors within the biometric data. The visual acuity was improved significantly in all patients after the phacoemulsification surgery.Conclusion:
The study confirmed that there is no significant difference between the refractive status predicted from Immersion A-scan biometry with the refractive status achieved post cataract surgery.
