无干预：对照：无 Systane iLux 处理

白内障手术前两周基线访视时未接受 Systane iLux 治疗。

实验性的：Systane iLux 治疗

Systane iLux 在白内障手术前两周基线访视时给药。

设备：Systane iLux 治疗

Systane iLux 是一种经批准的热脉动设备，用于治疗干眼病。 对双眼睑进行加热和加压，可融化阻塞腺体中的睑脂，以恢复眼睛睑脂的分泌和产生。 Systane iLux 仅用于进行白内障手术的眼睛。

Change in Lipid Layer Thickness (LLT) From 2 Weeks Pre-operative Baseline to 4 Weeks Post-operative Follow-up

Lipid layer thickness (LLT) was measured using LipiView II and reported in nanometers (nm). Higher values indicate a thicker lipid layer and improved tear film stability. Assessments were performed at both time points in the eye undergoing cataract surgery (one eye per participant). Change was calculated as the value at 4 weeks post-operatively minus the value at baseline. Negative values indicate a decrease from baseline.

Change in Standard Patient Evaluation of Eye Dryness (SPEED) Questionnaire Score From 2 Weeks Pre-operative Baseline to 4 Weeks Post-operative Follow-up

The SPEED questionnaire assesses dry eye symptom severity on a scale from 0 to 64, with higher scores indicating more severe symptoms. Assessments were performed at both time points. Change was calculated as the score at 4 weeks post-operatively minus the score at baseline. Negative values indicate improvement in symptoms.

Change in Ocular Surface Disease Index (OSDI) Questionnaire Score From 2 Weeks Pre-operative Baseline to 4 Weeks Post-operative Follow-up

The OSDI questionnaire assesses dry eye symptom severity on a scale from 0 to 100, with higher scores indicating more severe symptoms. Assessments were performed at both time points. Change was calculated as the score at 4 weeks post-operatively minus the score at baseline. Negative values indicate improvement in symptoms.

Change in Meibomian Gland Score From 2 Weeks Pre-operative Baseline to 4 Weeks Post-operative Follow-up

Meibomian gland morphology was assessed using infrared meibography with the LipiView II system. Gland dropout was graded on a standardized ordinal scale from 0 to 3 (0 = no gland loss; 3 = >66% gland loss), with higher scores indicating greater structural gland loss. Assessments were performed at both time points in the eye undergoing cataract surgery (one eye per participant). Analyses were conducted at the participant level. Change was calculated as the score at 4 weeks post-operatively minus the score at baseline. Positive values indicate worsening gland loss.
