Objective. To evaluate the immediate and long-term biological and functional results of reconstructive penetrating keratoplasty (RPKP) in the children. Materials and methods. We undertook a comparative analysis of the outcomes of 86 cases of the surgical intervention on 74 children presenting with corneal opacities of different etiology who had been treated with the application of reconstructive penetrating keratoplasty based at the Department of Eye Pathology in Children, The Helmholtz Moscow Research Institute of Eye Diseases. All operations were made by the same surgeon during the period from 2008 to 2014. The results of reconstructive penetrating keratoplasty were compared with the outcomes of conventional penetrating keratoplasty. The biological results were evaluated in terms of the graft survival (Kaplan-Meir’s) model. The duration of the postoperative follow-up period ranged from 5 months to 8 years and averaged 20,8 ± 9,7 months in the children treated with the use of reconstructive penetrating keratoplasty and to 3,0 ± 15,4 months in the patients treated by means of conventional penetrating keratoplasty. Results. During the early postoperative period (within 1 and 6 months after surgery), the difference in the graft survival rate between the two groups was practically non-existent. After 1 month, the transparency of the transplanted cornea was fairly well preserved in the children of both groups, but persisted for 6 months only in 72% and 95% of the patients treated by reconstructive and conventional penetrating keratoplasty respectively. One year after surgery, the graft survival in the children treated with the use of reconstructive penetrating keratoplasty was documented in 54% of the cases in comparison with 78% in the patients treated by means of conventional penetrating keratoplasty. The difference between the two groups was statistically significant (p < 0,05). Two and three years after surgery, the transparency of the transplanted cornea in the children treated with the use of reconstructive penetrating keratoplasty fell down to 50% and 20% respectively. During the same periods, the transparency of the transplanted cornea in the children treated by means of conventional penetrating keratoplasty remained as high as 76% and 62% respectively. Conclusion. Although the combination of penetrating keratoplasty with other surgical modalities results in the almost three-fold reduction of the probability of engraftment of the transparent corneal transplant in the remote postoperative period in comparison with the standard implantation of the donor cornea transplant, this operation provides the only possibility for the restoration of vision in the children suffering from severe corneal pathology.

Summary The aim of the retrospective study was to analyze results after penetrating keratoplasties in patients with bullous keratopathy. The study included 60 patients with bullous keratopathy who underwent penetrating keratoplasty for the period 1990-2011, at the Eye Clinic of Pleven University Hospital. The average age of patients was 67 years (range 29-84 years). Additional risk factors were registered in 22.67% of the patients. Early postoperative complications occurred in 56.79%. In the early postoperative period, 81.31% of the patients had clear graft and improvement of visual acuity was achieved in 83.77%. In the late postoperative period, the graft failed in 28.95% of the patients. These results suggest that bullous keratopathy is an important complication after cataract surgery, and improvement of vision is possible only with keratoplasty.

The Impact ◽  
Tube Shunt

Intrinsic to glaucoma surgery using a tube shunt is the management of early postoperative hypotony. This consideration is unavoidable in all cases when using a tube shunt without an intrinsic valve and must still be considered in tube shunts that contain a valve, as the valve may not function as anticipated. Unfortunately, in the attempt to avoid hypotony and its associated complications, we are faced with elevated intraocular pressure (IOP) and its associated difficulties. However, the attempt to control IOP is not the only consideration when anticipating intentional tube occlusion. Additional factors such as technical complexity of the procedure, predictability of IOP in the early postoperative period, potential to reverse occlusion either partially or completely, and the impact on the long-term function of the tube shunt must be considered. The desired endpoint when occluding a tube intentionally is the complete prevention of flow to the tube shunt reservoir. The standard ways to occlude the tube are an external encircling ligature or an internal occluding suture, otherwise known as an “obturator” or a “ripcord,” or some combination thereof. With the external suture technique, prior to placing the reservoir, a 7–0 or 8–0 polyglactin 910 (Vicryl™ , Ethicon, Inc., Somerville, New Jersey) suture is tightly tied around the tube approximately 4–6 mm from the reservoir (Figure 35.1). It is anticipated that this suture will dissolve in about one month, opening the tube. However, the timing of opening may be highly variable between individuals, and that variability may be problematic. Alternatively, a 9–0 polypropylene suture can be placed around the tip of an anterior chamber tube with release performed by laser lysis. To prevent the polypropylene suture from floating freely in the anterior chamber after release, a pass should be made through the wall of the tube during placement. Alternatively, with the “ripcord” technique, the end of a 3–0 polypropylene suture without the needle is threaded into the distal opening of the tube at the reservoir for a distance of 4–6 mm.
