“…3,[5][6][7] Combined surgery is effective in lowering IOP but carries risk of postoperative complications and failure. [8][9][10] The incidence of complications can be reduced by adopting the new surgical technique of safe surgery system trabeculectomy developed by Peng Khaw at Moorfields Eye Hospital. 11,12 It is an evidencebased, step-by-step approach to trabeculectomy surgery that preserves vision in patients with glaucoma by minimizing complications while maintaining a desired IOP.…”

Purpose To determine the efficacy of safe surgery system trabeculectomy combined with manual small incision cataract surgery/ phacoemulsification in primary glaucoma coexistent with cataract. Methods This is a retrospective analysis of 105 cases who underwent single-site combined surgery between January 2008 and December 2009. Safe surgery system trabeculectomy with diffuse and posterior application of mitomycin C was performed in all cases. Cataract extraction was done either by Manual Small Incision Cataract Surgery (MSICS) or phacoemulsification. Main outcome measures were success rate of trabeculectomy, as determined by four different IOP goals and incidence of postoperative complications. Analysis was performed using R-2.15, and the significance was tested at 5% level. Results The minimum follow-up period was 12 months. The overall success rates (with or without medication) when safe surgery system trabeculectomy was combined with MSICS were 91, 70, and 51% for IOP r18, r15, and r12 mm Hg, respectively, and target IOP was achieved in 72% cases. The mean IOP reduction was 43.8% with MSICS and 42.08% with phacoemulsification. The surgical outcome was not significantly different for both techniques. Postoperative complications were infrequent and comparable. Conclusion The Safe Surgery System Trabeculectomy combined with cataract surgery offers excellent IOP control with minimal postoperative complications. It offers an effective and improved solution for primary glaucoma coexistent with cataract found in developing countries.

“…A recently published evidence-based update mentioned that the existing data in the literature regarding the effect of CE on bleb function have been inconclusive. 12 In the present series, considerable fluctuations in IOP occurred during the first few postoperative weeks and required additional medical therapy. The IOP control tended to stabilize after the second postoperative month.…”

“…The implication is that when IOP is of paramount importance, it may be better to separate the cataract and trabeculectomy procedures. 12 Phacoemulsification appears to have fewer adverse effects on the postoperative IOP control than a standard ECCE. 7 Advantages of phacoemulsification over ECCE include a smaller incision, more controlled anterior chamber depth during the intra-and postoperative period and fewer intraoperative manipulations resulting in better IOP control.…”

Purpose To evaluate the outcome of cataract extraction (CE) after glaucoma filtering surgery (GFS). Methods A total of 77 eyes (77 patients) who underwent CE with posterior chamber intraocular lens (PCIOL) implantation following GFS by a single surgeon were reviewed. Main outcome measures were preoperative and postoperative intraocular pressures (IOPs), visual acuities, medications, astigmatism, bleb survival, time of surgical failure, complications, and success rate. Results Mean time interval between GFS and CE was 46.8750.9 months (range, 2-348 months). The mean preoperative IOP was 13.974.7 mmHg (range 3-27 mmHg) and mean postoperative IOP at 3 weeks was 13.675.5 mmHg (range, 6-44 mmHg). The mean follow-up was 19.5720.1 months (range, 1.4-73 months; median 10.6 months). Complete success was achieved in 59 eyes (76.7%). The cumulative probability of complete success was 91.373.7, 82.075.6 and 78.176.5% at the end of 6 months, 1, and 2 years, respectively. Visual acuity before CE was p20/50 in all eyes (100%). Visual acuity at last visit was X20/40 in 33 eyes (42.8 %), 20/50-20/80 in 30 eyes (39.0%), p20/100 in 14 eyes (18.2%). Risk factors identified for qualified success included age at CE460 years, interval of p5 months between GFS and CE, use of preoperative glaucoma medications, and postoperative IOP 419 mmHg within 2 weeks. Conclusions IOP and bleb function was maintained after CE with PCIOL implantation following successful GFS with good visual recovery.

“…In fact, a large proportion of visually impaired users have more than one coexisting vision impairments. Patients having both cataract and glaucoma are quite frequent [16]. Studies of the National Eye Institute [30] show that about 4.5 % of the overall population has some form of color blindness, while about 45 % of people around 75 years old have cataract.…”

Traditional multimedia search engines retrieve results based mostly on the query submitted by the user, or using a log of previous searches to provide personalized results, while not considering the accessibility of the results for users with vision or other types of impairments. In this paper, a novel approach is presented which incorporates the accessibility of images for users with various vision impairments, such as color blindness, cataract and glaucoma, in order to rerank the results of an image search engine. The accessibility of individual images is measured through the use of vision simulation filters. Multi-objective optimization techniques utilizing the image accessibility scores are used to handle users with multiple vision impairments, while the impairment profile of a specific user is used to select one from the Pareto-optimal solutions. The proposed approach has been tested with two image datasets, using both simulated and real impaired users, and the results verify its applicability. Although the proposed method has been used for vision accessibility-based reranking, it can also be extended for other types of personalization context.
