“…The presence of vitreous prolapse in the anterior chamber should be noted as well as the integrity of the iris and capsule. Of note, high frequency ultrasound has shown to be better than slit lamp examination in assessing capsular support for sulcus IOL implantation [8]. If there is an intraocular lens in place, the type of lens and degree of dislocation should be assessed.…”

Secondary intraocular lens (IOL) implantation has evolved over the past few decades. Several new techniques, lens options, and materials now exist. Careful patient selection is important to determine the optimal secondary IOL technique. Intraocular lens placement in the capsular bag is the most ideal followed by sulcus placement. However, the best option when no capsular support exists in an aphakic patient remains unclear. Surgeons should be aware of contraindications for each technique; however, there are several situations where anterior chamber intraocular lens (ACIOL), scleral-fixated intraocular lens (SFIOL), and iris fixation can all be used. In those cases, surgeon familiarity and comfort with the secondary IOL technique can determine the type of surgery performed.

Purpose This is a prospective investigational study that was performed at Tanta University Eye Hospital, Tanta, Egypt to evaluate the role of ultrasound biomicroscopy (UBM) in planning secondary implantation of intra ocular lens (IOL) in aphakia. Methods Preoperative UBM was performed for the assessment of anterior segment of 30 aphakic eyes admitted for secondary IOL implantation with special attention to central corneal thickness (CCT), anterior chamber depth (ACD), ciliary sulcus (CS), anatomical changes, and posterior capsular (PC) integrity which had been assessed by measuring the remnants of PC with special attention to the 12, 3, 5, 6, 7, and 9 o'clock meridians. Results This study involved 30 eyes in 27 patients; 16 males and 11 females. The mean age was 8.39 ± 2.36 years. The causes of aphakia were: congenital cataract extraction in14 eyes (46.7 %); trauma in 14 eyes (46.7 %); and after extracapsular cataract extraction in 2 eyes (6.6 %). The mean CCT was 0.61 + 0.35 mm and the mean ACD was 3.03 + 0.41 mm. The ciliary sulcus was patent in 28 eyes (93.4 %). Posterior synechia was observed in 8 eyes (26.7 %), lens remnants in 11 eyes (36.7 %), corneal scars in 11 eyes (36.7 %), and vitreous in anterior chamber in 1 eye (3.3 %). The integrity of PC was illustrated with a diagram. Conclusions UBM is a useful device to evaluate aphakic eyes before secondary IOL implantation through good evaluation of the anterior segment with special attention to the posterior capsular integrity, ciliary sulcus, anterior chamber depth, corneal thickness, and detection of any structural changes in the anterior segment resulting from the remote cause of aphakia.
