Purpose: Correlation of pre‐operative anterior segment parameters with intra‐operative complications in cases of PEX undergoing phacoemulsification surgery.

Methods: Demographic details and anterior segment parameters of 51 cases of cataract from May 2018 to May 2019 and diagnosed to have PEX based on slit‐lamp biomicroscopy examination undergoing phacoemulsification surgery willingly giving consent to participate in the study were recorded. Parameters included were cataract grade, central corneal thickness, axial length, keratometry readings, intra‐ocular pressure, AS‐OCT parameters. Intra‐operatively pupillary dilatation and complications were recorded under the headingsiris prolapse, pupillary miosis, iris billowing, floppy iris, iatrogenic iris injury, rhexis extension, posterior capsular rent without vitreous leak, posterior capsular rent with vitreous leak, zonular dialysis, iridodialysis, cortex drop, nucleus drop and aphakia.

Results: Demographic parameters showed remarkable variability where Male: Female 3:1, age 54‐78 no association with consanguinity and diabetes mellitus as opposed to already known facts. Eight cases had iris prolapse, 8 cases of pupillary miosis, 8 patients had floppy iris, 9 patients had iris billowing, Zonular weakness and dialysis was noted in 3 cases. Correlation with anterior segment parameters was done using chi square test for categorical variables and unpaired t‐test for continuous variables using SPSS version 22. It was found that denser the grade of the cataract more likely the chance of iris being floppy.

Conclusion: PEX though well described in cold climate is also prevalent in tropical country like India with distinct demographic characteristics and is also associated with floppy iris syndrome, the risk for this being cataract grade.
