(ambil bacaan dalam diopter)

repeat 3 times for one eye. Doing for LE(occlude right eye) and BE (no need occlude both eye) also.so, total 9 times..(dalam hati, pt kata bosan2..haha..)

normal accommodation: 18.5 - (pt age/3)

eg: pt age 21

18.5 - (21/3) = 11.5

If the result is less than normal, maybe patient has problem.

Usually patients who are 40 years above have low accommodation and known as presbyopia. They difficult to see near target, they will remove spec and long their arm during reading newspaper.
