The main advantages and disadvantages of the various silicone buckles

Main disadvantages	Main advantages	Type of buckle
• Buckle effect only where the tire is located, needs very precise placement	• Wide buckle effect	Silicon tires
	• Minimal danger of infection
• Cannot be stretched
• May cause anterior-segment ischemia if sutured too tight
• Narrow buckle effect (usually used in addition to vitrectomy)	• Fast and easy procedure	Silicon band
• Danger of scleral erosion	• Minimal danger of infection
• Danger of infection	• Fast and easy procedure	Silicon sponge
	• Wide buckle effect: the buckle produces a useful slope, requires mild tightening
	• The buckle effect increases in a few hours by absorbing fluid from surrounding tissue
	• Minimal danger of anterior ischemia
	• No danger of intrusion
