“…It is known that Meibomian gland dysfunction and deterioration of the tear film may increase after cataract surgery [ 40 , 41 , 42 ]. However, the exact mechanism by which cataract surgery impairs the Meibomian gland function remains unknown.…”

The aim of the study was to analyze the prevalence of ocular demodicosis and ocular surface conditions in patients selected for cataract surgery. Eyelashes from 73 patients selected for cataract surgery were evaluated at × 40 and × 100 magnification using light microscopy. The anterior segment was assessed with the slit lamp. Additionally, Schirmer I and break up time (BUT) tests were carried out before surgery and 1 and 3 months postoperatively. A specially designed questionnaire containing e.g. information about chronic skin and eye diseases, previous ophthalmic surgeries, and patient's hygiene habits was used to assess the demographic variables. A majority of patients were at the age of 70–79 years, and there were more females (83%) in the study group. Demodex folliculorum was found in 48% of the patients. There was a correlation between the number of parasites and the presence of blepharitis, discharge at eyelid margins, and conjunctival hyperemia. Schirmer I and BUT test results were lower in patients with Demodex infestation before and after cataract surgery. The higher number of mites was correlated with lower Schirmer I test results postoperatively. The presence of Demodex mites influences the conjunctiva and lid margins leading to inflammation. The higher number of Demodex mites disturbs the tear film over time after cataract surgery.

“…Park et al have reported abnormal meibomian gland function as the cause of dry eye related to cataract surgery 12 . In another study authors have found thinning of lipid layer after cataract surgery 13 . These changes in the pre-corneal tear film make it less stable leading to development of dry eye 14 …”

PurposeThe objectives of the study were to identify the incidence and pattern of dry eye after phacoemulsification and manual small incision cataract surgeries.MethodsThe study consisted of two groups of patients - Group 1 underwent manual small incision cataract surgery (SICS) and Group 2 underwent phacoemulsification. The dry eye-related data was collected preoperatively and at 1 week, 1 month and 3 months postoperatively. Ocular Surface Disease Index questionnaire, tear break-up time (TBUT) and Schirmer test – 1 were used to record the type of dry eye.ResultsOne hundred eyes of 96 patients, including 35 (36.5%) men and 61 (63.5%) women with the mean age of 63.1 (±8.3) years were studied. Dry eyes were found in 42% eyes (p < 0.001) of patients at 1 week follow-up. Fifteen percent and 9% of the eyes were dry at 1 month and 3 months after surgery, respectively. There were 34 (53.1%) and 8 (22.2%) dry eyes in SICS and phacoemulsification groups, respectively at one week postoperative follow-up which was a statistically significant difference.Majority of eyes (27/42, 64.3%) had mild dryness. There were significant differences in TBUT at 1 week, 1 month and 3 months postoperatively. At 1 week review, the SICS group had mean TUBT of 10.0 (±0.55) sec as compared to 13.9 (±0.70) sec in phacoemulsification group (p < 0.001).ConclusionIncidence of dry eye is higher in SICS than phacoemulsification due to tear film instability. The clinicians should be conscious about dry eye symptoms and signs in an otherwise healthy eye after cataract surgery.

“…LipiView interferometry was applied to evaluate the tear film LLT and to monitor blinking patterns by capturing 20 s videos. The LLT results were converted from interferometric colour units into nanometres and the numbers of incomplete blinks and total blinks were calculated [14].…”
