Relationship between lens and capsular bag size.
OBJECTIVE
To measure the size of the lens and the empty capsular bag and evaluate the relationship between them.


METHODS
Iladevi Cataract & IOL Research Centre, Ahmedabad, India.


METHODS
In 46 eye-bank eyes, the equatorial diameter of the lens was measured after a corneoscleral button and the iris were removed. Empty capsular bag diameter was measured after extracapsular cataract extraction through an intact capsulorhexis.


RESULTS
Mean lens size was 10.20 mm +/- 0.38 (SD) and mean capsular bag size, 10.38 +/- 0.35 mm. The difference between the size of the lens and that of the empty capsular bag varied from 0 to 0.50 mm (mean 0.20 +/- 0.17 mm). Lenses measuring less than 10.25 mm in diameter showed an increase of 0.25 mm while lenses larger than 10.25 mm showed an increase of 0.09 mm.


CONCLUSIONS
Lens size was larger in our population than in previous studies. The increase in the empty capsular bag size was related to initial lens size.
