Micro-tip Castroviejo scissors have ultra-narrow, sharply tapered tips with blades sharpened all the way to the point, enabling ultra-precise cuts in delicate tissues like conjunctiva or nerves. Regular Castroviejo scissors typically feature thicker, broader tips and less refined blade geometry, which reduces control in tight or microsurgical fields. Micro-tip models often include spring-action or flat-pattern handles to improve dexterity and reduce hand fatigue during extended, high-precision procedures.
