Purpose
To compare the higher order of aberrations in different types of cataract
Setting
Tertiary private eye hospital, Mumbai, India
Methods
It’s a retrospective study where subjects diagnosed with cataract were included. Subjects who underwent cataract workup, including ocular biometry, higher-order aberration measurement, and objective grading of cataract using pentacam were included. Subjects with nuclear sclerosis (NS) grade II with and without cortical (CO) and/or posterior subcapsular (PSC) cataract were included. Subjects with NS III-IV, hypermature cataract or missing data were excluded. We chose NS grade II cataract as it is commonly presented in clinic. Subjects were divided into 4 different groups: only NS, NS+CO, NS+PSC and NS+CO+PSC. One-way ANOVA and post HOC Tukey test were used to compare the lenticular HOA at 4mm pupil size among different types of cataract.
Results
A total of 58 eyes were considered for analysis, where 25 eyes had NS, 14 had NS+CO, 10 had NS+PSC, and 8 had NS+CO+PSC. Coma (F=4.60, p=0.006), quadrafoil (F=2.86, p=0.04) and secondary trefoil (F=3.31, p=0.027) statistically significant different. Post hoc tukey revealed coma, quadrafoil, and secondary trefoil were higher in NS+PSC, NS+CO+PSC, and NS+CO group, respectively. Other HOAs were found to be comparable among different groups.
Conclusions
Lenticular Coma, quadrafoil, and secondary trefoil were found to be significantly higher in eyes with NS plus PSC, NS plus PSC plus Cortical opacity, and NS plus cortical opacity eyes, respectively.
