—We appreciate Dr Mackool's interest in our article on the intraocular lens fixation and continuous circular capsulorhexis. Dr Mackool first questions if the contracture of the capsular bag is related to the damage to the BAB. Indeed, a capsular contracture is often seen in patients with diabetes or glaucoma where the BAB is assumed to be damaged. However, the size of capsulorhexis did not change during the observation period in any of the cases included in the study. Dr Mackool next suggests that some metabolic or degenerative chemical responds to the fluorophotometry. This was unlikely because baseline fluorescence, ie, natural fluorescence, in the anterior chamber was always much less than the fluorescence following intravenous injection of sodium fluorescein.
