“…Bandage CLs, specifically, have been used over the last four decades in clinic after refractive surgery to aid patient recovery. They provide a physical barrier that allows the tissue to heal, and apply pressure to relieve pain [200]. Generally, the patient needs to continuously use soft bandage CLs after ophthalmic surgery, in order to sustain sufficient ocular surface hydration, protect the eye from necrosis, and improve comfort after surgery [201].…”

“…However, their use for extended period leads to tissue swelling due to their low gas permeability. Balafilcon A (Pure Vision, Bausch & Lomb), Lotrafilcon A (Night & Day, Ciba Vision), and Lotrafilcon B (O 2 Optix, CIBA Vision) are silicone hydrogels approved by the FDA for use as bandage CLs for extended period of time (6, 30, and 30 days after refractive surgery, respectively) [200,202,203].…”

Closure of ocular wounds after an accident or surgery is typically performed by suturing, which is associated with numerous potential complications, including suture breakage, inflammation, secondary neovascularization, erosion to the surface and secondary infection, and astigmatism; for example, more than half of post-corneal transplant infections are due to suture related complications. Tissue adhesives provide promising substitutes for sutures in ophthalmic surgery. Ocular adhesives are not only intended to address the shortcomings of sutures, but also designed to be easy to use, and can potentially minimize post-operative complications. Herein, recent progress in the design, synthesis, and application of ocular adhesives, along with their advantages, limitations, and potential are discussed. This review covers two main classes of ocular adhesives: (1) synthetic adhesives based on cyanoacrylates, polyethylene glycol (PEG), and other synthetic polymers, and (2) adhesives based on naturally derived polymers, such as proteins and polysaccharides. In addition, different technologies to cover and protect ocular wounds such as contact bandage lenses, contact lenses coupled with novel technologies, and decellularized corneas are discussed. Continued advances in this area can help improve both patient satisfaction and clinical outcomes.

“…The healing process occurs around the fourth postoperative day 18, 19. It is assumed that a delay in contact lens removal contributes to a higher risk of infection; however with prophylactic use of topical antibiotics, BCL could be held longer which may provide more stable and enhanced epithelial healing and less discomfort.…”

PurposeTo compare the outcomes of bandage contact lens (BCL) removal on the fourth versus seventh post-operative day following photorefractive keratectomy (PRK).MethodsThis study recruited eyes of patients who underwent PRK surgery. The patients were randomly assigned to 2 groups. In Group 1 BCL was removed on the 4th postoperative day, while in Group 2, BCL was removed on the 7th postoperative day. After BCL removal, patients were asked to express their pain score and eye discomfort. At one and three months follow-up examinations, visual acuity scale was assessed. Slit-lamp examination was performed in all visits to evaluate complications.Results260 eyes of 130 patients underwent PRK. The age and sex ratio were not significantly different between the two groups. One month after the surgery, the logMAR uncorrected distance visual acuity (UDVA) and corrected distance visual acuity (CDVA) were significantly lower in Group 2 (P value = 0.016, 0.001 respectively), however, the UDVA and CDVA were not significantly different after 3 months (P > 0.05). In Group 1, filamentary keratitis (FK) was observed in 10 (7.6%) eyes, 6 (4.61%) eyes were diagnosed with recurrent corneal erosion (RCE) and corneal haze was detected in 3 (2.3%) eyes. However, in Group 2, RCE was observed in 4 (2.3%) and FK was noted in 4 (3.07%) eyes. No haze was seen in Group 2. The difference in rate of complications was statistically significant (14.6% and 6.1% in Groups 1 and 2, respectively, P = 0.02). Pain and eye discomfort scores were not significantly different (P > 0.05). There was no major complications including infectious keratitis in either groups.ConclusionFollowing PRK surgery, BCL removal on the seventh postoperative day yields faster visual rehabilitation and lower rate of postoperative complications with no increase in eye pain, discomfort or infection.

Contact lenses-parameters, characteristics of the polymers • Dynamic development of contact lenses has been observed in recent years. Their diversity allows to choose those that are tailored to the individual needs. Soft lenses are becoming more popular and most people are wearing them constantly selecting monthly lenses instead of day lenses due to the lower cost of their use. Lenses made with newer materials such as lotrafilcon A and balafilcon A are used as a dressing lens for continuous wearing after surgery. The combination of hydrogel and silicone allows to achieve the comfort of wearing a soft hydrogel lenses with even higher solubility of oxygen in the silicone. Important parameters defining contact lenses are hydration, oxygen permeability coefficient, refractive index and Young's modulus. Development of soft contact lenses technologies as a drug carriers concern for example: incorporation of nanocapsules, liposomes or molecular printing.
