Quantitation of Corneal Ablation by Ultraviolet Laser Light

Deviations of Lambert-Beer’s law affect corneal refractive parameters after refractive surgery

“…1, the correlation is higher when including a non-linear term. This tendency is similar with other experimental data [10][11][12].…”

Ablation rate of PMMA and human cornea with a frequency-quintupled Nd:YAG laser (213 nm)

“…8). At 193 nm, the corneal ablation threshold measured by different research groups varied from 30 mJ/cm 2 [25] to 50 mJ/cm 2 [5,18]. We found that the cornea ablation threshold for the 213 nm was < 72 mJ/cm 2 and the ablation rate curve appearance (Fig.…”

“…Different lasers have been used to study the ablation rate of cornea tissue [5][6][7][8][9][18][19][20][21][22][23][24][25]. Two methods were most commonly used.…”

“…8) suggests that it might be < 50 mJ/cm 2 . When the radiant exposure was below 200 mJ/cm 2 , the ablation rates of 213 nm and 193 nm were similar [5,[21][22][23]25]. For example, at 120 mJ/cm 2 , the ablation rates of 213 nm and 193 nm were both in the range of 0.12-0.17 m per pulse.…”

“…For example, at 120 mJ/cm 2 , the ablation rates of 213 nm and 193 nm were both in the range of 0.12-0.17 m per pulse. However, the ablation rate of 213 nm increased gradually faster as radiant exposure increased when compared with the 193 nm excimer laser [5,18,19,[21][22][23][24][25]. When the radiant exposure was increased over 250 mJ/cm 2 , the ablation rate for 213 nm was between 1.2 and 2.2 times faster than the ablation rate for 193 nm (Fig.…”
