Effect of hydroxypropyl methylcellulose as compared to the technique of hydro-implantation of intraocular lens during phacoemulsification on post operative intraocular pressure.
J Sharif Med Dent Coll Jan ;2(01):7-9.

Objective: To compare the effect of hydroxypropyl methylcellulose as compared to the technique of hydro-implantation of intraocular lens during phacoemulsification on post operative intraocular pressure. Methodology: This prospective interventional study included 90 patients who were divided into two groups A & B. All patients underwent routine phacoemulsification with intraocular lens implant. In group A, lens was implanted after inflating the capsular bag with hydroxypropyl methylcellulose where as in group B, the technique of hydro-implantation was used. Pre operative and post operative intraocular pressure was measured and compared. Results were considered significant when p-value was <0.05. Results: In Group A, the difference in pre and 24 hours post operative intraocular pressure was statistically significant (p-value 0.028) whereas in Group B, the difference was not statistically significant (p-value 0.67). Also there was statistically significant difference in the 24 hours post operative intraocular pressure between Group A and B (p-value 0.036). At one week post intervention, there was no statistically significant difference between post operative intraocular pressure of Group A and B (p-value 0.39). Conclusion: Hydro-implantation does not result in the spike of intraocular pressure as observed in the first 24 hours post phacoemulsification as compared to implantation of intraocular lens using hydroxypropyl methylcellulose.
