Post Operative Complications

Background: Artificial intelligence (AI) is becoming ever more frequently applied in medicine and, consequently, also in ophthalmology to improve both the quality of work for physicians and the quality of care for patients. The aim of this study is to use AI, in particular classification tree, for the evaluation of both ocular and systemic features involved in the onset of complications due to cataract surgery in a teaching hospital. Methods: The charts of 1392 eyes of 1392 patients, with a mean age of 71.3 ± 8.2 years old, were reviewed to collect the ocular and systemic data before, during and after cataract surgery, including post-operative complications. All these data were processed by a classification tree algorithm, producing more than 260 million simulations, aiming to develop a predictive model. Results: Postoperative complications were observed in 168 patients. According to the AI analysis, the pre-operative characteristics involved in the insurgence of complications were: ocular comorbidities, lower visual acuity, higher astigmatism and intra-operative complications. Conclusions: Artificial intelligence application may be an interesting tool in the physician’s hands to develop customized algorithms that can, in advance, define the post-operative complication risk. This may help in improving both the quality and the outcomes of the surgery as well as in preventing patient dissatisfaction.

Post Operative Complications

Background: Despite significant advances in canine cataract surgery over the years, many post-operative complications persist and reduces the success rate of phacoemulsification procedure. The aim of current study was to evaluate post-operative complications encountered till 90 days after bimanual phacoemulsification with implantation of different acrylic Intraocular Lenses.Methods: The study was conducted on 24 canine eyes. All the clinical cases were subjected to detailed ocular, ultrasonography and neuro-ophthalmic tests for ascertaining cataract and associated neuro-ophthalmic pathology. Dogs were divided in four groups with 6 eyes in each group and subjected to phacoemulsification procedure for removal of cataractous lens and implanted with square edge or round edge hydrophilic or hydrophobicintra ocular lenses.Result: Statistically non-significant (p£0.05) variations were found for all the post- operative complications among the groups. Within the groups initially higher values were recorded and on subsequent days a declining trend of varying degrees were observed. The corneal opacity was a major postoperative complication leading to failure to achieve vision with other coinciding neuro-ophthalmic conditions.

Post Operative Complications

AbstractThis study consisted of the evaluation of the plain X-ray findings of films taken at early follow-up (mean 1.5 months after surgery) and at late follow-up(4–14 years after the early films) of 211 ears which had been operated on radically and obliterated. Residual cells which were detected on the basis of the early films were associated with a more frequent occurrence of post-operative infection and were thus hallmarks of a poorer prognosis. Changes in the bone surrounding the surgical cavity and the radiological quality of the walls of the surgical cavity, the presence of new bone formation in the cavity and other radiological features did not yield useful information about post-operative complications. New bone formation was associated with a smaller amount of post-operative cavitation. Post-operative X-ray examination of the obliterated ear is a prognostically useful examination, but it does not significantly contribute further to the information available by clinical and otomicroscopic examination in regards to the complications of infection and cholesteatoma.

Post Operative Complications

Purpose – The purpose of this paper is to determine the safety of substituting the first day post-operative review after routine cataract surgery (phacoemulsification) with a telephone survey. Design/methodology/approach – Prospective non-randomised cohort study. A standardised questionnaire of five common ocular symptoms (general condition, vision, eye pain, headache, nausea or vomiting) was administered by a trained nurse on the first post-operative day. The patients were reviewed in clinic two to 14 days later. Patient charts were retrospectively reviewed for complications (endophthalmitis, raised intra-ocular pressure, wound leaks and uveitis) requiring deviation from standard treatment. Findings – Over 13 months, 256 eyes of 238 patients underwent uncomplicated phacoemulsification by four consultant surgeons. Only one patient reported poor general condition, blurred vision and eye pain. She was subsequently found to have corneal oedema and raised intra-ocular pressure when recalled for an earlier review. Best corrected visual acuity better than 20/40 was achieved in 80.5 per cent of patients. There were no other post-operative complications noted from medical records review. Research limitations/implications – Non-randomised nature, skewed surgical expertise, lack of a control group and patient experience data. In all, 22 patients (9.2 per cent) were also uncontactable for the telephone interview. Practical implications – A nurse-administered telephone survey seemed to be a safe and effective alternative to first day post-operative review after routine phacoemulsification. The survey also enabled the detection of serious post-operative complications. The first day post-operative hospital visit may be safely substituted in a selected patient population with greater patient convenience achieved and liberation of clinic resources. Originality/value – This is the first study which utilises a standardised questionnaire as a form of post-operative review in an Asian population.
