*Abbreviations CW and MP in this table connote continuous wave and micropulse exposures, respectively.

†The number of times that delivered corneal energy exceeds ANSI Z136.1‐2000 maximum permissible exposure (MPE)¹³ for corneal energy. For a 125 μm retinal laser spot size diameter, 810 nm, 0.2 second envelope, 500 Hz exposure of 100, 0.3 ms micropulses, C_A = 1.660 and C_E = 4.902. C_A is the correction factor used to increase MPE values in the near infrared (IR‐A) due to decreased RPE absorption in IR‐A.¹³ C_E is the correction factor used to calculate the ocular extended source MPE from the small source MPE when the laser source subtends a visual angle greater than α_min (the apparent visual angle which divides small source from extended source viewing).¹³

‡(power)×(duration)×(duty factor) = (1800 mW)×(0.2 s)×(0.15) = 54 mJ

¶As noted in table 1, micropulse lesions were not demonstrable in this patient even with power settings 6× MPE.
