-4.50+/-2.25 (-1.50 to -12.50)
-4.44+/-2.12 (-1.75 to -11.00)
Rs.post
-0.15+/-0.10 (-1.37 to +1.25)
-0.10+/-0.09 (-1.00 to +1.12)
CRc
-4.15+/-2.06 (-1.47 to -9.72)
-4.08+/-1.77 (-1.62 to -9.50)
Kpre
44.15+/-1.47 (41.12 to 47.62)
44.04+/-1.48 (41.12 to 47.95)
Kpost
41.25+/-1.92 (36.37 to 45.43)
41.17+/-1.84 (36.81 to 46.60)
All measured values are in Diopters where Rs.pre = pre-Lasik spectacle correction,
Rs.post = post-Lasik spectacle correction, CRc = amount of myopia corrected at the
corneal plane, Kpre = pre-Lasik corneal power, Kpost = post-Lasik corneal power,
Each group consisted of 100 cases. Group I was used to establish the formulas to
calculate Kc.rd and Kc.cd and Group II was used to validate the results.
The results show the average, standard deviation and the range of these values.
