However, mechanical pupil dilation is very helpful in achieving and maintaining the mydriasis when all other strategies failed. The studies showed dramatically increased rates of intraoperative pupil instability and miosis varying from 1.65% to 64%. Comparison of various pupil dilatation methods for phacoemulsification in eyes with a small pupil secondary to pseudoexfoliation Ophthalmology. Wolters Kluwer Health [19] Epinephrine alone can be added to irrigation solution for the intracameral administration to achieve sustainable mydriasis during cataract procedure.[20].

[33] One of the hooks located adjacent to and below the main corneal tunnel retracts the iris downward and prevents it from being in the path of the ultrasonic needle. Each device is introduced into the eye with the specially designed forceps. Blurry vision can be the telltale sign of cataracts and may worsen over time if left untreated. LASIK is the best known and most commonly performed. In cataract surgery, the presence of small pupils (SPs) presents a major challenge [ 1 ]. Over the years, the idea of designing the pupil expansion ring was very attractive. Surgeons generally recommend pupils that are at least 7 mm wide when conducting cataract surgery. The latter increases the risk of capsular contraction and phimosis leading to progressive zonular weakness and intraocular lens-capsular bag complex dislocation in the delayed postoperative period. A manipulator is used to facilitate placement of the device feet that catches the iris edge and expand the pupil. Choosing the correct refractive power in the lens implanted in the eye during cataract surgery is vitally important to restoring clear vision. Inadequate preoperative mydriasis and/or intraoperative miosis might result in iris trauma and photophobia.

[35] These rings are relatively difficult to handle during the surgery, not very stable in the eye and may require significant time and efforts to implant and remove. Being relatively simple and effective in many cases, this manipulation may not provide sufficient mydriasis, cause iris bleeding and pupil atony postoperatively.[29].

[36] The profile is thinner as compared to preexisting rings, making it easier and safer to manipulate inside the eye. implants let all the light thru so everything is brighter and pupils get smaller. [44], However, NSAIDs administered topically 13 days before FLACS significantly reduced the chances of pupil constriction following femtosecond laser delivery into the eye.

In 2008, femtosecond laser-assisted cataract surgery (FLACS) was introduced into clinical practice. Recently, more interventions and instruments are available for the cataract surgeons to deal with these challenging cases. This condition, known as congenital miosis or microcoria, causes nearsightedness and could eventually lead to glaucoma; more likely than not affecting one eye than the other. However, this type of strategy can be more successful if the patient's iris maintains rigidity compared to the patients whose irises are biomechanically unstable such as in cases with IFIS.
