[Correlations between ocular biometry and post-surgical refraction].
OBJECTIVE
To show the importance of ocular biometry in establishing the power of intraocular lens.


METHODS
We studied 212 eyes operated in the University Eye Hospital from Cluj-Napoca by planned extracapsular extraction with intraocular lens implantation. Before operation there was performed ocular biometry, using SRK II formulas for calculation of intraocular lens. At 6 weeks after operation, we checked the ocular refraction by dioptronometry and we established the optical correction of the patients.


RESULTS
The standard error was statistically significantly in all cases. In 84.19% of cases it was performed visual acuity with optimal correction over 0.7.


CONCLUSIONS
The ocular biometry represents significant factor in obtaining a very good visual acuity after cataract operation.
