Purpose Povidone-iodine (PI) is widely used to reduce the preoperative conjunctival bacterial load. This study aimed to evaluate the employment of PI 10% in an attempt to sterilize the ocular surface prior to cataract surgery, and to show that PI could be left in contact for 3 minutes. The viability of this exposure time in clinical practice, associated adverse events, and visual outcomes were documented. Methods In this prospective cohort study, phacoemulsification cataract surgery was performed in 604 patients by a single surgeon. Preoperative preparation was undertaken with PI 10%, applied to the cornea, conjunctival sac, eyelids, and periorbital skin with sterile cotton gauze. Povidone-iodine was then flushed onto the ocular surface. Operating room staff timed the precise duration of exposure. After the 3-minute preparation, the lids were thoroughly dried with fresh dry gauze. Results The median PI exposure time was 3.17 minutes, with an interquartile range of 0.25. All cases were followed up postoperatively at 1 day, 1 week, and 1 month. There were no complications attributable to PI. Visual outcomes were satisfactory. Conclusions Implementation of a preoperative prophylaxis protocol that used PI 10% with a 3-minute exposure time can be performed in clinical practice. The 3-minute exposure time had no adverse sequelae.

A multicenter, nonrandomized, prospective, controlled study was conducted to evaluate, as perioperative prophylactic treatment, the anti-infective effectiveness of 0.66% povidone-iodine eye drops (IODIM®) against the bacterial flora of the conjunctival surface of patients who undergo cataract surgery. Eye drops containing 0.66% povidone-iodine were applied to the eye undergoing cataract surgery; the untreated contralateral eye was used as control. One hundred and twenty patients set to receive unilateral cataract surgery were enrolled in 5 Italian Ophthalmology Centers and pretreated for three days with 0.66% povidone-iodine eye drops. The contralateral eye, used as control, was left untreated. Conjunctival swabs of both eyes were collected at the baseline visit and after three days of treatment, just before the cataract surgery. A qualitative and quantitative microbiological analysis of bacterial presence was evaluated by means of bacterial culture, followed by identification. Methicillin resistance determination was also performed on staphylococci isolates. Bacterial load before and after treatment of the eye candidate for cataract surgery was evaluated and compared to the untreated eye. A reduction or no regrowth on the culture media of the bacterial load was observed in 100% of the study subjects. A great heterogenicity of bacterial species was found. The 0.66% povidone-iodine eye drops, used for three days prior to cataract surgery, were effective in reducing the conjunctival bacterial load. The 0.66% povidone-iodine eye drops (IODIM®) might represent a valid perioperative prophylactic antiseptic adjuvant treatment to protect the ocular surface from microbial contamination in preparation of the surgical procedure.

Purpose. To investigate the association among the ocular surface temperature (OST), tear film stability, functional visual acuity (FVA), and blink rate in patients after cataract surgery. Methods. We recruited 98 eyes of 69 patients (mean age, 73.7 ± 5.2 years) 1 month after phacoemulsification with implantation of acrylic intraocular lenses and assessed slit-lamp microscopy, corrected distance VA, FVA, noninvasive tear breakup time (NIBUT), and OST. We defined the changes in the OST from 0 to 10 seconds after eye opening as the ΔOST. We measured the FVA and blink rate using the FVA measurement system. We divided the patients into two groups based on tear film stability: stable tear film (NIBUT, >5.0 seconds) and unstable tear film (NIBUT, ≤5.0 seconds). We evaluated the differences between the two groups and the association between the blink rate and other clinical parameters. Results. The unstable tear film group (56 eyes) had significantly (p<0.0001, unpaired t-test) shorter NIBUTs than the stable tear film group (42 eyes). The ΔOSTs and blink rates were significantly (p<0.0001) higher in the unstable tear film group than in the stable group. Linear single regression analysis showed that the ΔOST (r = −0.430, p<0.0001), NIBUT (r = −0.392, p<0.0001), and gender (r = −0.370, p=0.0002) were correlated significantly with the blink rate. Multiple regression analysis showed that the ΔOST independently contributed to the blink rate. Conclusions. The frequency of blinks is associated with tear film stability in patients after cataract surgery. The blink rate may be useful for evaluating the tear film stability in clinical practice. The ΔOST should be an important contributing factor to the blink rate. [This trial is registered with UMIN000026970].

Accuracy Of Measurements

Aim To review published literature concerning cataract surgery and dry eye disease (DED). Methods A search was undertaken using the following: PubMed (all years), Web of Science (all years), Ovid MEDLINE(R) (1946 to 12 December 2019), Ovid MEDLINE(R) Daily Update 10 December 2019, MEDLINE and MEDLINE non-indexed items, Embase (1974–2019, week 49), Ovid MEDLINE (R) and Epub Ahead of Print, In-Process and Other Non-Indexed Citations and Daily (1946 to 12 December 2019), CENTRAL (including Cochrane Eyes and Vision Trials Register; Cochrane Library: Issue 12 of 12 December 2019), metaRegister of Controlled Trials (mRCT) ( www.controlled-trials.com ), ClinicalTrials.gov ( www.clinicaltrial.gov ) and WHO International Clinical Trials Registry Platform ( www.who.int/ictrp/search/en ). Search terms included ‘cataract surgery’, ‘phacoemulsification’ and ‘cataract extraction’, combined with ‘dry eyes’ and ‘ocular surface’. Relevant in-article references not returned in our searches were also considered. Results Publications identified included systematic reviews, meta-analysis, randomized controlled trials, cohort studies, case series and laboratory-based studies. Published data highlighting the burden of DED both prior and following cataract surgery were reviewed as well as studies highlighting the effects of cataract surgery on the ocular surface, intra-operative measures to reduce deleterious effects on the ocular surface and current evidence on the management options of post-operative DED. Conclusions DED is common and can be exacerbated by cataract surgery. Ophthalmologists need to assess for pre-existing DED and instigate treatment before surgery; be aware of reduced accuracy of measurements for surgical planning in the presence of DED; limit intra-operative surgical factors damaging to the ocular surface; and consider management to reduce DED post-operatively.
