Abstract Aim of study was to assess the visual acuity (VA) before and after correction with soft and rigid gas permeable contact lenses (CLs) in healthy subjects, as well as their visual perfomance, including contrast sensitivity function (CSF), and twilight vision (TV). 60 eyes corrected with soft contact lenses (SCLs) and 38 eyes with rigid gas permeable contact lenses (RGPCLs) were enrolled in this prospective study. The following measurements were obtained: best spectacle–corrected visual acuity (BSCVA), best contact lens-corrected visual acuity (BCLCVA), TV, and CSF. Parameters were evaluated before and after CLs fitting and 2 months after the baseline. Exclusion criteria included anterior and posterior segment pathology, amblyopia, prior CLs wear, and ocular surgery. When analyzing TV, results showed superiority of CLs to the spectacle correction, with no statistical difference regarding the CL type. As for the CSF, RGPCLs were superior to both SCLs and spectacle correction. Visual performance was better in group fitted with RGPCLs oppose to SCLs group. CL wear improved visual performance compared to spectacles. This is the first prospective study to simultaneously investigate changes in VA, CS, and TV in SCL and RGCL wear, suggesting RGPCLs as the correction of choice for achieving optimal visual performance.

AbstractGold eyelid implantation is widely considered the procedure of choice to reanimate the upper eyelid in paralytic lagophthalmos. Commercially supplied implants are not readily available in all places and are sometimes cumbersome to import.Objective:We aimed to devise a method whereby every surgeon performing gold eyelid implantation could have easy and quick access to the implant. Furthermore, we aimed to develop a means of creating an implant of the exact weight required for complete eyelid closure.Study design and setting:A prospective study was performed from 1997 to 2005 in a tertiary research hospital, involving 50 subjects requiring gold upper eyelid implantation and using the technique in question.Results:Only patients with a minimum follow up of one year were included in the study group. Symptoms improved in 96 per cent of subjects, who were able to dispense with eyedrops and eye ointments. Visual acuity improved in 92 per cent of patients. There were two extrusions amongst the early cases.Conclusion and significance:Customised gold eyelid implantation offers an alternative in regions where commercial implants are not easily obtained.

A Prospective Study

Background: The aim of the study is to investigate whether the circadian IOP rhythm can be influenced by combined cataract surgery with high frequency deep sclerotomy (HFDS) and whether intraocular pressure (IOP) can be significantly reduced by HFDS. Methods: In our study 10 patients were included, in whom 24 h IOP monitoring was installed before and after HFDS/cataract surgery using a Triggerfish. HFDS is a minimally invasive glaucoma surgery (MIGS). Results: After performed HFDS combined with cataract surgery, the IOP was reduced from 27.7 ± 2.11 mmHg to 14.4 ± 2.59 mmHg, which is highly significant (p < 0.001). The contact lens sensor (CLS) cosinor analysis pre- and postoperatively showed that the circadian rhythm is not influenced by the surgery, i.e., the circadian IOP rhythm did not show significant differences before and after surgery. Conclusions: HFDS combined with cataract surgery is a potent surgical method that can significantly reduce the IOP. However, the circadian rhythm cannot be changed by the surgery. The acrophase remained during the night in all patients.

Aim A prospective study was undertaken to assess the diagnostic value and therapeutic usefulness of fibreoptic bronchoscopy in the critically ill. Method Fifty-six bronchoscopies were performed in fifty patients. Biochemical, radiological, microbiological and clinical assessments were made before and after each procedure. Results Eighteen fibreoptic bronchoscopies were performed for therapeutic indications (32.1%) of which ten (55.6%) yielded a useful outcome. Thirty-eight bronchoscopies were for diagnostic purposes (67.8%) of which 22 (5 7.9%) were clinically useful. Broncho-alveolar lavage was performed in twenty-eight cases (50%) and it led to a clinically useful diagnosis in 17 (60.7%). There was no major complication. A subgroup of patients was defined (persistent left lower lobe collapse or consolidation following thoracic or abdominal surgery) in whom fibreoptic bronchoscopy usually did not yield a useful outcome. Conclusion The use of fibreoptic bronchoscopy in the Intensive Care Unit, in combination with the technique of broncho-alveolar lavage, results in a clinically useful outcome in the majority of cases. Fibreoptic bronchoscopy is an effective and safe diagnostic and therapeutic tool in critically ill patients.
