Ophthalmic surgeries on porcine eyes with picosecond ultrashort laser pulses.

Purpose: This work demonstrates significant advantages in ophthalmic surgeries through the use of picosecond ultrashort laser pulses instead of state-of-the-art nanosecond laser pulses. These ultrashort lasers shall serve as universal tools more effectively combining advantages of high precision, low impact and economic advantages compared to existing instruments.

Methods: As samples, we used post-mortem porcine eyes on which we performed the experiments with both picosecond and nanosecond lasers.
