  • Title: [Lens position following planned capsular sac fixation: results of 200 consecutively surgically treated phacoemulsifications].
    Author: Duncker G, Wetzel W.
    Journal: Fortschr Ophthalmol; 1990; 87(2):140-3. PubMed ID: 2358269.
    Abstract:
    A total of 200 phacoemulsifications with planned in-the-bag fixation of one piece PMMA posterior chamber lenses implanted consecutively by one surgeon were examined on postoperative days 3-7. Special attention was given to both position of the haptics and centering of the lens. No sodium hyaluronate or other viscoelastic materials were used in any of the operated eyes. After capsulorhexis and phacoemulsification inside the bag we were able to confirm in-the-bag fixation in 190 implants (95%). In 197 of the 200 patients centering of the IOL was excellent. The capsular rim of the circular capsulorhexis was preserved in all cases due to phacoemulsification within the capsular bag. This procedure meets the best conditions for a secure in-the-bag insertion of the posterior chamber lens. Expression of the lens nucleus after capsulorhexis or through the so-called letter-box technique leads to a remarkably lower percentage of proven bag-bag fixation of the haptics.
