Abstract:
Purpose: To compare different commercial viscoelastics retained in the anterior chamber in terms of their tendency to cause intraocular pressure (IOP) rise Methods: Twenty-one rabbit eyes (3 per group) were injected with 0.1 mL of viscoelastic materials (VEM). Seven different brands of VEM were tested. IOP was measured for 6 days after injection Results: All eyes exhibited increase from baseline IOP. Peak IOP rise occurred at a median with 4 hours from injection. IOPs returned to normal in all eyes by Day 6. No significant differences in IOP patterns were detected in this small series Conclusion: This study suggests that all of the VEM tested have potential to cause IOP rise and that spontaneous return to normal levels was achieved for all groups after six days.
