21 participants in 2 patient groups

Post surgery without glaucoma drops

Active Comparator group

Description:

This will be for the group that had gas duration surgery using SF6 (Sulfur Hexafluoride) or C3F8 (perfluoropropane gas tamponade) and only uses the standard post-operative topical drops.

Treatment:

Drug: standard post-operative topical drops

Post surgery with glaucoma drops

Experimental group

Description:

This will be for the group that had gas duration surgery (using SF6 or C3F8). In addition to the standard post-operative topical drops, glaucoma drops, Timolol-dorzolamide (timolol 0.5%-dorzolamide 2%) will be given.

Treatment:

Drug: Timolol-dorzolamide (Glaucoma drops)

Drug: standard post-operative topical drops
