Using Surgical Microscope for Sclera Buckling and Transscleral Cryopexy: An Alternative Procedure of Treatment for Rhegmatogenous Retinal Detachment

Table 3

Comparison of surgery using surgical microscope versus using indirect ophthalmoscope for scleral buckling and transscleral cryopexy.

	Using surgical microscope	Using indirect ophthalmoscope
Advantages	Continuous zoom (no need for accommodation of naked eye of operator)	Wide view
	Erect image	Stereopsis
	Easy to suture accurately	Posterior pole can be seen easily
	Pre-equatorial and peripheral retina can be seen easily
Disadvantages	Need to press peripheral retina strongly	Inverted image
	Impossible to see posterior pole	Hard to see details of retina
	Narrow view	Need for accommodation of naked eye of operator
