[Centering intraocular lenses with reference to capsular incision].

BACKGROUND

Can the capsulotomy with small radial incisions compared to the continuous curvilinear capsulorhexis with perfect IOL centration still be recommended? This problem should be clarified under standard conditions.

METHOD

On 100 patients both procedures were applied alternating with corneoscleral incision, phacoemulsification and endocapsular implantation of a 6 mm one-piece PMMA lens.

RESULTS

The perfect IOL-centration following capsulorhexis (0.25 +/- 0.31 mm) is confirmed. But the circular capsular fibrosis can make it difficult to examine the fundus periphery or to perform a secondary cataract aspiration. The IOL centration after capsulotomy is not always ideal (0.55 +/- 0.51 mm) but sufficient. Advantages are the simplicity of the procedure and an easy approach to the posterior capsule in case of secondary cataract.

CONCLUSION

Both methods are still appropriate.
