“…These results are in accordance with those obtained by Keates et al, since they found that the majority of IOP returned to the pretreatment level in 1 week post capsulotomy. 23 In relation to visual field examination, we used the programme 24-2, which is accepted nowadays as the standard, given that it contains 99% of the information provided by 30-2 but is 25% faster, so it involves less fatigue, and therefore less short-term fluctuation. 24,25 The visual fields inclusion criterion was established in less than 20% for both false-positive and false-negative errors.…”

Purpose Although posterior capsular opacification (PCO) is a common phenomenon in a considerable number of ophthalmologic patients, no prospective controlled trials assessing its influence on automated perimetry exist. This technique continues as a standard in the diagnosis of glaucoma and neuroophthalmological diseases. The aim of the present report is to investigate the effect of PCO on automated visual field examination. Methods A total of 26 PCO affected eyes of 26 patients had Humphrey SITA standard (program 24-2) immediately before, and between 1 and 8 weeks after Neodymium : YAG capsulotomy. The effect of learning associated with repeated testing was controlled with automated perimetry before enrolment and visual fields of the fellow eye. Best-corrected visual acuity (BCVA), intraocular pressure (IOP), and global perimetric pre-and post-laser indices were compared using the Student's t-test for paired samples. Correlation and linear regression analyses were also performed. Results BCVA and mean deviation (MD) improved following capsulotomy. Pattern standard deviation (PSD), an indicator of localized defects in the field, also improved significantly when PCO was solved. Moreover, a strong association among BCVA, MD, and PSD was shown both prior to and after capsulotomy. Conclusion PCO is a heterogeneous mean opacity. This polymorphism may alter visual field results, and may even simulate the perimetric behaviour of other pathologies such as glaucoma. Consequently, the presence of PCO should be considered in the interpretation of any automated perimetry in pseudophakic patients. In addition, the values obtained before capsulotomy may partially predict the values obtained after capsulotomy.

“…Although, Nd:YAG laser is a safe and noninvasive technique for PCO, it is not without complications, some of which can be sight threatening. 1 The technique of incision in cataract surgery has evolved from the conventional, large 12 mm wound closed with multiple sutures to small incision sclera tunnel and now to clear corneal tunnel incision. This incision used in phacoemulsification allows faster postoperative recovery and visual rehabilitation with minimum discomfort and less incidence of postoperative astigmatism.…”
