“…The most frequently observed complications in contact lens wearers are: Inflammatory infiltrates, corneal ulcer, giant papillary conjunctivitis, and bacterial keratitis, which account for 25%–60% of complications in SCL wearers worldwide. [ 20 ] Furthermore, most contact lens wearers (over 80%) use SCL, which accounts for approximately 70% of cases of bacterial eye infections. [ 37 ]…”

“…Although new technologies have been searching for more efficient products for the safety and comfort of contact lens wearers, the main risks are still related to hygiene practices as well as overnight use of the lenses. [ 20 ] Our results suggest that the patients may not have correctly adhered to good hygiene practices in the handling of contact lenses, a habit that should be encouraged through training and use of efficient evaluation means by ophthalmologists. [ 57 ]…”

PURPOSE: Certain ocular resident or pathogenic microbes may remain viable in the presence of multi-purpose disinfectant solutions (MPDSs), subsequently developing biofilms inside contact lens storage cases (CLSCs) which pose a risk of infection to wearers. This study evaluated the formation of ocular microbiota biofilms exposed to three top selling MPDS. METHODS: Crystal violet assay was carried out for the verification of biofilm formation. The in vitro assays evaluated Pseudomonas aeruginosa UFPEDA 416 and Staphylococcus aureus UFPEDA 02 exposure of 48 h to MPDS, as well as the use of 40 KHz ultrasound at the beginning and with 24 h immersion in the MPDS. Subsequently, in vivo assays evaluated the formation of microbial biofilms on the CLSC walls containing silicone-hydrogel contact lenses immersed in MPDS from 15 healthy volunteer patients, who had been wearing the lenses for 7 days. RESULTS: Biofilms were inhibited by 26%–98% in the in vitro assays, with a statistically significant difference only for P. aeruginosa UFPEDA 416 exposed to diluted MPDS. Most inhibitions occurred moderately and weakly. In addition, adherent cells were detected in more than 90% of the tests. Biofilm was not inhibited in more than one third of the results, nor was it disturbed, especially with the ultrasound treatments. The average of obtained optical densities at 590 nm was between 0.6 and 0.8 in the in vivo assays. The results were similar between the CLSC right and left wells. There was a correlation between microbial biofilm formation and the type of MPDS tested, with statistical difference between the three treatments. CONCLUSION: MPDS promoted a partial inhibition of microbial biofilm formation but only one MPDS proved to be more effective in vitro and in vivo. This study, however, could not distinguish the effect of possible errors in the good hygiene practices of the users.

“…7,9 Dry eye, big papillary conjunctivitis, corneal abrasion, corneal oedema, corneal ulcer, keratitis, and neovascularisation are common conditions experienced by contact lens users. 10,11 The younger generation was unaware of these effects, and 87% of users still preferred contact lens use for cosmetic reasons despite ocular problems. 12,13 Ocular health education can aid in preventing difficulties brought on by improper contact lens-wearing behaviour by raising awareness of prudent and safe practices.…”

Introduction: The study’s objective was to evaluate the knowledge, attitudes and practises of pharmacy students at St Johns College in Yemmiganur, Andhra Pradesh, India, regarding the use of contact lenses. Method: A semi-structural questionnaire was provided to conclude the inquiry. The questions were in English and covered wearing contacts, taking care of them, problems they can create with their eyes, and their advantages. 65 (46 female and 19 male) of the 175 Pharm D students and 139 (95 female and 44 male) of the 406 B Pharmacy students participated in the study while using contact lenses. Result: 7.91% of B Pharm and 13.84% of Pharm D students used contacts for cosmetic purposes, 25.97% (27.33% of B Pharm and 24.61% of Pharm D) for refractive correction, 7.08% (6.47% of B Pharm and 7.69% of Pharm D) for headache relief, and 56.05% (58.27% of B Pharm and 53.84% of Pharm D) for both cosmetic and refractive purposes. Most of them wore soft contact lenses. The most frequent issue (30.93% of B Pharm and 27.69 % of Pharm D) of students who wore contacts was pain, which was followed by redness and irritation. Even though 23.96% (18.70% of B Pharm and 29.23% of Pharm D) also utilised water, the students chose lens solutions because they were aware of their options. Conclusion: The majority of participants had no idea what these problems were. All businesses that sell contact lenses ought to inform their customers more thoroughly about contact lens issues and lens maintenance.

“…Keratitis has been widely reported in patients with soft contact lenses, but rarely in patients wearing rigid gas permeable contact lenses. 1,2 To the best of our knowledge, the occurrence of infection associated with three species of pathogens has never been reported. This report describes the treatment of a patient who exhibited mixed triple corneal infection, as well as similar cases previously reported in the literature, to discuss appropriate treatment for these types of complex corneal infections.…”

There have been numerous reports regarding the occurrence of keratitis in patients with soft contact lenses, but few reports in patients with rigid gas permeable contact lenses. To the best of our knowledge, the occurrence of infection associated with three species of pathogens has never been reported. Here, we describe a patient who exhibited refractory painless keratitis caused by three pathogens (Staphylococcus epidermidis, Acanthamoeba, and herpes simplex virus) and summarize similar reports published at multiple centers worldwide, with the aim of providing guidance for clinicians who might encounter mixed-type corneal infections. We describe the results of many ophthalmologic and laboratory investigations, which guided our treatment selection. We achieved good treatment efficacy, such that the patient exhibited a corrected visual acuity of 20/20 in the affected eye after a series of treatments, including curettage of ulcer lesions. Corneal infections caused by multiple pathogens are challenging in clinical practice. This summary of our experience in patient diagnosis and treatment can help clinicians to achieve a favorable prognosis in treatment of future patients.
