A long-term clinical outcome of Hoffmann pocket four-point scleral fixated intraocular lens implantation combined with penetrating keratoplasty - A single corneal surgeon's report.

Purpose: To analyze retrospectively the outcomes of Hoffmann pocket scleral fixated intraocular lens implantation combined with penetrating keratoplasty at a tertiary institute by a single corneal surgeon. Methods: Forty-two eyes of 42 patients, aged between 11 and 84 years, had a mean follow-up of 2 ± 2.216 years. Overall, five (11.9%) had congenital and 37 had acquired pathology, 15 were pseudophakic, 23 were aphakic, and four were phakic. The commonest indication was trauma in 19 (45.2%), and 21 had previous multiple surgeries including five retinal procedures. Results: The grafts were clear in 20 (47.6%), they failed in 20, three had acute rejection, three were ectatic, two had infection, one had persistent edema, and one had endophthalmitis. The mean log of minimum angle of resolution (logMAR) best corrected visual acuity was 1.902 pre-op, 1.802 at the final follow-up, and 0.52 after excluding preexisting retinal pathologies. At the last follow-up, the vision improved in 18 (42.9%), maintained in 6, and worsened in 18, and three needed more than -5.00 D and seven needed more than -3.00 D cylinder correction. Five had glaucoma preoperatively, 10 developed the condition postoperatively, six needed cyclodestructive procedure, and three had valve surgery. Conclusion: Advantages of this surgery are avoidance of additional sections to insert the lens, direct positioning of the lens in the posterior chamber, rotational stability of the lens from four-point fixation, and untouched conjunctiva over the scleral pockets. The fact that 20 had clear grafts and 18 visually improved, though two needed lens removal and one developed retinal detachment postsurgery is encouraging. More cases with longer follow-ups will help understand the technique better.
