Data Preprocessing for Quality Analysis of Contact Lens Material in Ophthalmology using Factor Analysis

This paper focuses on Factor analysis performed on contact lens material. The Factor Analysis on the contact lens material and interpretation are the central steps in this research process. The extracted contact lens data are comprehended and interpreted to trigger the research. Analysis based on a wide range of variables can be tedious and time consuming. The contact lens materials such as RGP, Soft and Hybrid are considered as the source of dataset for factor analysis. Principle Component Analysis is the method adopted to do Factor Analysis. From the result it is found, out of 10 parameters 5 parameters are considered to be the key parameters for identifying the quality contact lens material in the field of ophthalmology. Keywords— Contact Lens, RGP Lens, Soft Lens , Hybrid Lens, Factor Analysis, PCA, Ophathalmology.
