Schematic diagram of ophthalmic endoscopy. a Shows a straight endoscopy probe in proximity to the crystalline lens to emphasize that the risk of iatrogenic cataract can be reduced if the surgeon avoids passing instrumentation behind the posterior pole of the crystalline lens. b Shows how a curved endoscope probe can facilitate far periphery examination without crystalline lens injury. c Illustrates that a straight endoscopy probe can be used to cross behind the posterior pole of an artificial intraocular lens
