Correction of presbyopia; revision
While practicing last Monday, i asked a resident to prescribe reading glasses for a 50 year female who never wore glasses before
Her autoref readings where +3.0/-1.5 x 90
He prescribed
+5.0/-1.5 x 90 OU with acuity 6/6, this is VERY wrong (it seems he did not read my posts, i like learning by repetition so let’s repeat
1)do NOT prescribe cylinders for the first time above 40
2)i view of this we re-calculate the refraction as +2.0 SE OU
3)based on the power of accommodation at 50, distance correction is +1.0
4)NEVER increase reading glasses by more than 1.0 at a time
5)the final reading prescrition for this lady is +2.0 OU which can be bought ready made at the pharmacy.
It would be a shame for our practice that a patient finds that ready-made eye-glasses she bought from a cheap stand WAY more comfortable than our prescribed ones.
Please know how to prescribe GOOD glasses or surrender the job to optometrists.
