Purpose

To highlight the importance of Dysfunctional Lens Index (DLI) in preoperative evaluation of cataract surgery patients and its correlation to logMAR corrected distance visual acuity (CDVA) and lens grading opacification according to the Lens Opacities Classification System III (LOCS III).

Setting

Institute of Vision and Optics (IVO) Heraklion, Crete.

University Hospital of Heraklion, Crete.

Methods

The Dysfunctional Lens Index (DLI) feature of the iTrace wavefront aberrometer (Tracey Technologies, Houston, TX) was recorded in a total of 35 patients aged 60-years or older (mean age of patients: 77 years). Twenty-one of 35 patients were female while 14 were male. Measurements of logMAR corrected distance visual acuity (CDVA) and lens grading opacification according to the Lens Opacities Classification System III (LOCS III) were performed in all of the patients. Seven of these patients had been diagnosed with type 2 Diabetes Mellitus while none of the other patients reported any other significant past medical history.

Results

A total of 35 patients had low DLI (mean: 4,12), a number that showed negative linear correlation with the patients’ lens opacification degree (mean: 2) without taking into consideration the cornea abnormalities. The DLI additionally showed a higher negative linear correlation with the corrected distance visual acuity (mean: 0,3 logMAR) compared to lens opacification degree.

Conclusions

The DLI was correlated with the LOCS III nuclear opalescence score and CDVA.

Modalities such as lens densitometry, wave front aberrometry and light -scatter assessment can quantify optical aspects of cataract and may prove clinically useful in surgical evaluation. The iTrace DLI is precise as a numerical representation of the visual quality of a patient’s crystalline lens and it can help us to track the progression of nuclear cataract.
